## **Applications** 

Protection of people and machines Emergency stop circuits on machines Monitoring of safety gates 

Stop category 1 can be realised 

## **Indication** 

upper LED: on, when supply connected lower LEDs: on, when relay K1 and K2 resp. K1t and K2t energized 

## **Notes** 

To select automatic restart terminals 13 - 14 must be bridged. Open terminals 13 - 14 select manual restart, the On-button must then be connected to S33 - S34. 

Line fault detection on On-button: 

The line fault detection is only active when S12 and S22 are switched simultaneously. If the On-button is closed before S12, S31, S32 is connected to voltage (also when line fault across On-button), the output contacts will not close. 

A line fault across the On-button which occurred after activation of the relay, will be detected with the next activation and the output contacts will not close. If a line fault occurs after the voltage has been connected to S12, S31, S32, the unit will be activated because this line fault is similar to the normal On-function. 

The unit can be operated with single channel and 2-channel operation with cross fault monitoring. For connection please refer to application examples.

## **Notes** 

The gold plated contacts of the BH 5928 mean that this module is also suitable for switching small loads of 1 mVA - 7 VA, 1 mW - 7 W in the range 0,1 - 60 V, 1 - 300 mA. The contacts also permit the maximum switching current. However since the gold plating will be burnt off at this current level, the device is no longer suitable for switching small loads after this. The terminal S21 permits the operation of the device in IT-systems with insulation monitoring, serves as a reference point for testing the control voltage and is used to connect the E-stop loop when cross fault monitoring is selected. 

Connecting the terminal S21 to the protective ground bridges the internal short-circuit protection of Line A2(-). The short-circuit protection of line A1(+) remains active. 

Y39 - Y40 must be closed to have timed outputs. By opening the bridge between Y39 and Y40 the time delay can be interrupted immediately. Without bridge the contacts switch without delay. 

The time setting has to be sealed by the user after test.
