Three-phase monitoring relay
CM-PFS
The CM-PFS is a three-phase monitoring relay
that is used to monitor three phase mains for
incorrect phase sequence and phase failure.
All devices are available with two different terminal
versions. You can choose between the proven
screw connection technology (double-chamber
cage connection terminals) and the completely
tool-free Easy Connect Technology (Push-in
terminals).

F: red LED – fault message
Application
The CM-PFS is used to monitor three-phase mains for incorrect phase sequence and phase failure.
Operating mode
The three-phase main to be monitored is connected to terminals L1, L2, L3 in accordance to the wiring diagram.
The device operates according to the closed-circuit principle g – incorrect phase sequence or phase failure: relays de-
energize.
The signalling of status indication is made by means of the front-face LEDs.
Function diagram
Phase sequence and phase failure monitoring
If all phases are present with the correct phase sequence, the output relays energize after the start-up delay ts is complete.
If a phase failure or a phase sequence error occurs, the output relays de-energize instantaneously.
The LED R is on when output relays are energized.
In case of motors which continue running with only two phases, the CM-PFS detects phase failure if the reverse fed voltage
is less than 60% of the originally applied voltage.
