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.
