To that end, a team of quality auditors strictly matches the quality to industrial quality norms to ensure there is no slump in the quality. This package of quality is on offer at economical rates. Additional Information : In large installations with multiple emergency-stop buttons, it is useful to quickly know which emergency-stop button has been operated to minimize downtimes. For this application DOLD offer specific emergency stop button monitors with indication and bus outputs. Advantages Emergency stop modules Safety category up to EN 954, SC4 Safe thanks to potential-free contacts Miniaturization space saving designs Gold-plated contacts, for low loads Easy wiring saves cost Tailored to your applications Quick module replacement via detachable terminals Preconfigured type-tested modules save time and cost Emergency stop monitors Quick identification of the depressed emergency-stop button via clear LED indication Reduced downtime, due to fast location of the depressed emergency-stop button A choice of signalling to primary controls and displays via bus interface or BCD coded outputs. 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.

SAFEMASTER®M Our safemaster M as a compact modular safety system extends our consistent safety solution concept. It consists of 4 main modules : Control module Input module Output module and Diagnosis module The control module BH 5911 has inputs and outputs. It features the emergency-stop function, either 1- or 2-channel with manual or automatic start. 4 start keys as a maximum can be connected, which can be assigned to the control module or to the input modules in any combination. 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.

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 Information By 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 systems Text 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 principle For 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 principle The 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. Applications DOLD 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
