4.4  Failsafe Alarm Relay Wiring and Specifications 
 
The “Failsafe” output relay is provided to signal critical error conditions that may occur on the 
M2000 series products. The contacts are energized upon power up of the unit and remain 
energized until a critical error occurs. The proper relay connections are shown in Figure 10. One 
common application for this output is to signal an alarm if a power failure or removal of control 
power occurs.
