The Monitor Relay indicates the followings failures:
• Loss of power
• Stop by Torque out of limits
• Direction failure
• Temperature too high
• Position sensor failure
• Local control panel with selector in local position
• Valve jammed

The Monitor relay contacts can be set as CLOSE or OPEN by changing the welding of
JUMPER J31 on logic board. As a default setting, pins 2 and 3 are welded together, and the
Monitor relay contact operates as follows:
— contact CLOSE in normal condition with relay energized, and OPEN in
case of malfunction (relay is de-energized).
In case of request, if contact must be OPEN in normal condition and CLOSE in case of
malfunction, the contact of JUMPER J31 must be modied welding pins 1 and 2 together.
