As a well admired provider of Residual Current Monitor, we bring you a huge variety of unrivaled quality. Our team of experts uses only first-class raw materials to ensure that our product matches to the highest quality grades. It is the perfect solution for commercial application in both earthed and also non-earthed systems. The remarkable features like optimum performance and longer service life make it an interesting proposition. Additional InformationUnscheduled downtimes of machines and plants mean a considerable cost factor. By early detection of insulation faults DOLD insulation monitors help to prevent failures of electrical equipment and thus ensure a better operating reliability and plant safety. They are used both in earthed and also non-earthed systems, but differ in their function principle.   In earthed systems (TN systems) DOLD residual current monitors detect fault current with the principle of differential-current measurement and are mainly used to avoid cost-intensive downtimes and to prevent the risk of fire which is latent in the case of slowly evolving insulation faults. In non-earthed systems (IT systems), the insulation resistance to earth of the system to be monitored is measured. Such systems are secured by insulation monitors the use of them in IT systems is required by law by the norm “Safety of Machinery”  DIN EN 60204-1 or DIN VDE 0100-410.  Thanks to deliberately kept simple functionality of DOLD’s insulation monitors customers benefit from a considerable cost advantage combined with the high quality standard accustomed from DOLD.   Advantages At a glance: Save space thanks to compact design Cost-effective and easy-to-use by kept simple functionality Flexible by extended application range of our insulation monitors for systems up to 500V AC and 1000 Hz, i.e. also application for 400V three-phase systems Monitor DC systems up to 280V without auxiliary voltage Improve efficiency: avoid unscheduled downtimes and data losses Improve operational reliability and safety: monitor also at standstill, no interruption of operation in the case of single-phase-to-earth fault Better fire safety: detect slowly evolving insulation faults, minimize accidental arcs as frequent fire cause, split and separately monitor systems in fire- and explosion-prone areas Improve workplace safety: no malfunctions of machinery and systems due to earth faults Save time during maintenance and repair: reduce cost by early detection of insulation faults and well-aimed repair.   Technology All conductors of the feeder to be protected (apart from the protective conductor) are guided through a current transformer. In a faultless system, the sum of all currents is zero. No voltage is induced in the current transformer. If fault current flows via earth, the current difference will cause a current in the current transformer. This is evaluated by electronics.   Applications Differential-current and insulation monitors are used for early detection of insulation faults in applications where unscheduled downtimes of machinery would have serious consequences. They are used in earthed systems for reasons of efficiency and protection against fire and accidents, but they are required by law in non-earthed systems for the same reasons according to DIN VDE 0100-410 and DIN EN 60204-1. Applications include: Wood working industry: fire prevention Chemical industry: prevent the interruption of chemical production processes Automotive: prevent downtime of entire production lines if one partial area fails Food industry: prevent consequential losses, e.g. failure of a cooling plant Medical: prevent the failure of live-saving facilities Data processing: prevent data loss in computer centers, data processing equipment and systems.   Moreover, insulation monitors are used to monitor cut off consumers, which are only needed in certain situations, but must then function without problems, flue gas extraction systems in case of a fire, for example.

Depending on the model the safety-related output has either 3 NO contacts or 2 NO contacts plus 1 NC contact, each in redundant configuration. The input module BG 5913 has 8 safety-related inputs. Depending on the variant these inputs can be assigned to several safety functions. e.g. 1x safety gate + 1x ESPE + 1x emergency-stop or also 1x safety gate + 1x two-hand etc. These safety functions are processed in the input module and control the assigned output module(s). The output module BG 5912 consists of two positive-action relays, which may have a variety of contact complements depending on the variant. These include 3 or 4 redundant NO contacts or 2 NO contacts/1 NC contact or 3 NO contacts/1 NC contact. It goes without saying that also delayed safety-related outputs are available, with the time being adjustable on the module. Here, the combinations 3x NO or 2x NO/1x NC are possible. Where no potential-free relay output is required, we offer the module BG 5912.88 with safety-related off-delayed semiconductor outputs (stop category 1).  The model BG 5912.89 features 4 safety outputs and is only 22.5 mm wide. Two outputs have no delay (stop category 0) and the other two are off-delayed (stop category 1). Tailoring of the system to the relevant application is possible by using a control module which can be extended by up to 3 input and output modules each.Applications DOLD’s multifunctional safety systems provide optimized solutions for a variety of applications in machinery and plants, e.g. Paper and printing industry Forming Beverage industry Food industry Packaging industry Injection moulding machines Machine-tools Robot cells Wood working machines

Trusting on our industrial knowledge, we have cemented our status as a leading figure in the industry. We offer Fault Annunciator to our respected customers at attractive price. It is equipped with striking features such as lasting life, robustness and high performance. It is applied for monitoring purposes of machinery and plants of any type. Our excellent distribution system enables you to get it delivered to your doorstep in no time. Additional InformationBy lamps, buzzers or also in form of clear text DOLD fault annunciators inform on faults and conditions in electrical installations in industrial facilities and buildings. They also inform on work operations to be done. DOLD fault annunciators considerably reduce the time for fault finding in particular in complex machines and plants. Thus they help to minimize downtimes of production plants and save cost. Apart from simple electrical group fault, new-value and first-up annunciators, electronic clear text fault annunciating systems are available for complex applications. Especially when programmable logic controllers (PLC) or management systems are used it is indispensable to install fault alarm acquisition independent of the process level to keep control when the plant control fails and to avoid damages.   Applications Monitoring of machinery and plants of any kind Building monitoring   Advantages At a glance Cost-effective, compact monitoring of small machines without PLC, e.g. compressors. Modular design allows adjusting to plant extensions at any time (e.g. IL/SL 5990). Central monitoring of multiple PLCs or centralization of multiple alarm relays for an overall overview on machinery and plants. Allow selective indication of certain fault types on several monitoring centers. Group faults of the same type from many systems, channel and pass them well-aimed on to responsible expert personnel, e.g. insulation faults -> service electricians, low filling levels -> operating personnel, etc. DOLD’s text fault annunciators can be programmed in several languages, e.g. for foreign operating personnel. Statistics stored in the text annunciator help to optimize the plant operation. The products can be extended by a two-wire bus system. Open-circuit monitoring within the bus system when configured according to the de-energized on trip principle. Prevent damages to man and machine in case of faults or even PLC failure. Avoid costly production losses by early fault detection and thus allow the implementation of an improved operational reliability. Reduce the time for troubleshooting by early and easy fault localization. Save time for fault finding.   Technology Group fault, new-value and first-up annunciators have normally acoustic and visual indicators and are designed for DIN rail mounting or also for front panel mounting. Group fault annunciators are available for 4 up to 160 signals and energize a relay when a fault signal occurs. Such a relay can be de-energized by an acknowledging key. A visual (flash lamp) or an acoustic (horn) transducer is connected to this relay output. New-value and first-up annunciators are used where the chronology of fault signals is essential. The new-value annunciator signalizes that alarm among a number of alarms the status of which has changed last after the last acknowledgement. New-value annunciations are indicated by a flash lamp and after acknowledgement as permanent light until the fault is cleared. The first-up annunciator signalizes that alarm among a number of alarms the status of which has changed first after the last acknowledgement. The first occurred fault is indicated by a flash lamp and consequential faults by permanent light. Text fault annunciator systemsText annunciator systems echo the correct sequence of the arrived fault signals.  Stored alarms can be called up and viewed on the display. Text fault annunciator systems can be operated as new-value and also as first-up annunciators. Text fault annunciators have outputs for group annunciation, horn and system readiness. Inputs and outputs are metallically isolated and thus ensure a maximum of interference immunity. Beyond standard applications, statistics, analog processing, time interrupt functions, decentralized acquisition and output as well as multilingualism of the fault texts are customer-specific options. A printer can be used for logging, i.e. for printing date, time, and test of the fault and the whole statistics memory of the system. With appropriate programming software also other settings than message texts can be defined such as energized/de-energized-on-trip principle of inputs, delay of inputs as well as grouping and priority of outputs. A decentralized fault alarm acquisition in complex installations can be configured with up to 30 modules with 8, 16, 24 or 32 inputs each. Via a separate module, these modules are connected to a two-wire line which is connected to the central fault annunciator. A maximum of 957 fault alarms can be acquired with this. Additional remote control stations complete the system. De-energized- versus energized-on-trip principle De-energized on trip principleFor safety reasons DOLD recommends the de-energized-on-trip principle for fault annunciators. Here, the contact falls back in its normal position when the operating condition is met. Operating condition is loss of voltage which may be either due to a fault to be annunciated or to a fault in measured current transmission (e.g. damage of the supply cable). Thus, the wiring itself is included in the monitoring. Energized on trip principleThe contact switches to its operated condition when the operating voltage is present, i.e. a fault alarm is initiated by an electric signal. Disadvantage: If the supply conductor to the fault annunciator is interrupted, neither this interruption nor any other fault can be indicated by the device. This is why DOLD recommends the de-energized-on-trip principle.   ApplicationsDOLD fault annunciators are used to specify maintenance intervals for preventive maintenance and for general monitoring in following application areas (among others):  Industry : Production plants, production sequences and processes Machine functions, e.g. V-belt rupture, filter clogging, dry-running of pumps Compressors Buildings : Heating, ventilation and air condition (HVAC) Doors, gates and windows Transport and materials handling systems Environment : Power stations Sewage treatment plants Waste incinerating plants

Counting on our experience in the industry, we have positioned us in the upper echelons of the industry by offering unequaled quality in the form of Extension Modules. Our distribution network allows us to facilitate quick and convenient delivery in a matter of time at your doorstep. They are used for multiplying the output contacts of the basis modules. They also make it possible to contact reinforcement by splitting into multiple control circuits.  Extension modulesExtension modules can be used to multiply the output contacts of the basis modules. Also contact reinforcement by splitting into multiple control circuits is possible. Delay modulesThe emergency-stop of a dangerous movement can be accelerated by a controlled stop operation according to the stop category 1 by allowing motor brake functions or controlled drive speed reduction to run during the cutout delay. Coupling modulesCoupling modules with positively driven contacts are used to switch safety-related functions as links between logic circuitry and load. The positively driven NC contacts can be used to monitor the closing contacts.  From single function safety modules up to modular multifunction safety systems with field bus connections, designed to protect both man and machine. Sometimes it is not too easy for machine and system manufacturers and users alike to design safety-related circuits using discrete contactor hardware to comply with the abundance of regulations currently in place. To assist them, DOLD offer type-tested safety modules allowing tailored solutions to be installed with respect to functionality and cost.   Advantages Extension modules Cost-saving contact multiplication, universal connectivity to all basis modules Monitor output contacts via a feedback loop through the relevant basis module Connect multiple extension modules to a single basis module by cascading Delay modules Controlled stop operation of drives minimizes the risk of injuries No adverse effects on productivity as immediate restarting is possible High long-term stability by digital timer Coupling modules Very safe switching behaviour by positively driven contacts. Allow a regulation-compliant implementation of safety-related circuits. Prevent retriggering in the case of an error.   TechnologyExtension modules : Compact module with positively-driven safety relays which is triggered by the associated function module (basis module) and monitored via a feedback loop. An extension module can only reach the basis module's safety category acc. to EN 954-1 as a maximum. Delay modules : Delay-release time-delay relay with or without auxiliary voltage and adjustable or fixed time setting. High long-term stability thanks to digital timer. Two time circuits working independent of each other to implement a cutoff redundancy. Positively driven release contacts. Coupling modules : Coupling modules feature safety relays with positively driven contacts according to EN 50205. Positive-action is present if the contacts are mechanically linked to each other so that NC and NO contacts can never be closed at the same time. For this it must be ensured that a contact gap of at least 0.5 mm is present over the whole service life, even in fault condition. ApplicationsExtension modules : Multiplication of release circuits of a basis module to cut off any number of control circuits in a safety-related manner. Delay modules : Quick stopping of a dangerous movement of drives with masses.A typical example are tools rotating with high speed, which still coast after cutoff for a longer time. Coupling module : Used, for example, for self-monitoring safety circuits, for the adjustment of control and power levels and for switching safety-related functions.

Technology Emergency stop modules : The function of an emergency-stop module is to quickly and reliably stop a dangerous movement in when a potential hazard is identified. This is why appropriate circuits are incorporated to prevent failure of devices downstream from an emergency-stop control device. Dependent upon a risk assessment and the resultant safety category, these circuits are designed with the following features : Redundancy Cyclically monitored Fail-safe operation Further features Potential-free outputs with positively driven contacts Compliance with EN 954 Emergency stop monitors : The green status LED’s are illuminated for non-operated emergency-stop buttons. When an emergency-stop button is depressed, the associated LED will go out. The emergency-stop buttons are series connected; this is why only one LED will go out if multiple emergency-stop buttons are operated. In this case, only the depressed emergency-stop button which is closest to the front position in the emergency-stop chain is signaled.  When this emergency-stop button is unlocked, the next depressed emergency-stop button is indicated. Applications Emergency stop modules : Stop dangerous movements or cut off energy in case of danger to protect man, machine and product. They are used in machinery and plants which may cause danger to man or machine, e.g. in the packaging industry, production plants, food industry, material handling, plastic processing, steel and aluminium industry, woodworking industry. Emergency stop monitors : Monitor emergency-stop buttons in large plants to quickly locate the depressed emergency-stop button, e.g. in industrial applications, materials handling, sewage treatment and woodworking plants.
