The CM-SRS.M is an electronic current monitoring
relay that protects single-phase mains (DC or AC)
from over- and undercurrent from 3 mA to 15 A.
All devices are available with two different terminal
versions. You can choose between the proven
screw connection technology (double-chamber
cage connecting terminals) and the completely
tool-free Easy Connect Technology (push-in
terminals).

Application
The multifunctional current monitoring relays CM-SRS.M are designed for use in single-phase AC and/or DC systems for
over- or undercurrent monitoring. The devices operate over an universal range of supply voltages, provide an adjustable
start-up as well as tripping delay and work according to the open- or closed-circuit principle.
Operating mode
The CM-SRS.M with 2 c/o (SPDT) contacts are available in 2 versions with 3 measuring ranges: 3-30 mA, 10-100 mA,
0.1-1 A (CM-SRS.M1) and 0.3-1.5 A, 1-5 A, 3-15 A (CM-SRS.M2). The measuring range is selected by connecting the
monitored wire to the corresponding terminal B1/B2/B3-C.
The units are adjusted with front-face operating controls. The selection of over- b or undercurrent monitoring a, openh or closed-circuit principle g and latching function ON f or OFF e is made with DIP switches. Potentiometers, with
direct reading scale, allow the adjustment of the threshold value I, the hysteresis %, the tripping delay TV and the start-up
delay TS. The hysteresis % is adjustable within a range of 3 to 30 % of the threshold value and the tripping delay TV and the
start-up delay TS are adjustable over a range of instantaneous to a 30 s delay. Timing is displayed by a flashing green LED
labelled U/T.

Open-circuit principle h
Overcurrent monitoring
The current to be monitored (measured value) is applied to terminals B1/B2/B3-C. When control supply voltage is applied
to terminals A1-A2, the start-up delay TS begins. The green LED flashes X during the start-up delay TS and then
turns steady. During the start-up delay TS overcurrent is only displayed by glowing of the red LED.
If the measured value exceeds the adjusted threshold value, when TS is complete, the tripping delay TV starts and the red
LED glows. Timing of TV is displayed by the flashing W green LED. When TV is complete and the measured value still
exceeds the threshold value minus the adjusted hysteresis, the output relays energize and the yellow LED (relay energized)
glows.
If the measured value decreases below the threshold value minus the hysteresis, the output relays de-energize and the red
and yellow LEDs turn off. If control supply voltage is interrupted, the green LED turns off.

For usage of the current monitoring relays according to UL, following limitations for the measuring circuits are applicable: The load on any single measuring circuit should not exceed
15 A at 51-150 V, 10 A at 151-300 V or 5 A at 301-600 V.
This limitation is only valid for application according to UL and not for IEC applications.
