V1.1.0• Feedback loop for monitoring downstream contactors orexpansion modules• Cyclical monitoring of the output contacts • Indication of the switching state via LED • 2 start behaviors possible: - monitored manual start - automatic start• Short circuit and earth fault monitoring • Up to PL e, SILCL 3, category 4Correct UseESM-BT4.. is an emergency stop safety relay combination that combines non-time-delayed and time-delayed contacts in a very compact housing. This permits dangerous components of a system to be switched off quickly and safely in an emergency situation. At the same time, other circuits can continue to be supplied with voltage for up to 30 seconds to allow a tool to be moved to its idle position or to brake following parts, for exam-ple.Features• 4 positively driven safety relays contacts. Possible vari-ants:- 3 non-time-delayed and 1 time-delayed contact - 2 non-time-delayed and 2 time-delayed contact - 1 non-time-delayed and 3 time-delayed contact• Continuously adjustable time delay (1 to 30s) or fixed time delay (ESM-BT4..-20S (2s); ESM-BT4..-50S (5s)) • Connection of:- emergency stop buttons - safety switches- non-contacts safety switches - OSSD-Outputs• 1- or 2-channel activation possibleFunctionThe moving parts of a machine or system can be quickly and safely stopped in case of danger with the non-time-delayed contacts of the ESM-BT4...Safety contacts with time-delay switch-off are also integrated into the ESM-BT4... They are used whenever it is safer to keep supplying voltage to parts of a machine after the emer-gency stop switch is operated.It is ensured that a single fault or malfunction does not lead to a loss of the safety function and that every fault is de-tected by cyclical self-monitoring no later than when theInstallationAs per DIN EN 60204-1, the device is intended for installa-tion in control cabinets with a minimum degree of protection of IP54. It is mounted on a 35-mm DIN rail according to DIN EN 60715 TH35.system is switched off and switched on again. The time-delay contacts are activated at the same time asthe non-time-delay contacts; however, when the emer-gency stop button is pressed, the contacts are only deacti-vated after the time set on the potentiometer (1 … 30s) or after a fixed time delay (ESM-BT4..-20S; ESM-BT4..-50S).During timeout, no power-loss is accepted.Electrical ConnectionFig. 1 Block diagram: ESM-BT401 (1nd/3d); ESM-BT411 (2nd/2d); ESM-BT421(3nd/1d)V1.1.0Depending on the application or the result of the risk assessment according to EN ISO 13849-1, the device must be wired as shown in Fig. 1 to Fig. 11.
