Notes

Monitoring of Reset-button function: Monitoring of Reset-button function is only active when S12 and S22 are switched simultaneously. If the Reset-button is closed before S12, S22 is connected to voltage (also when fault across Reset-Button), the output contacts will not close. A fault across the Reset-button which occurred after activation of the relay, will be detected with the next activation and the output contacts will not close. If a fault occurs after the voltage has been connected to S12, S22, the unit will be activated because this fault is similar to the normal Reset-function. The gold plated contacts of the MSR23M 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.

Notes

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. Depending on the operation of the machine, the switch S1 is set to automatic or manual restart.
