Operating Instructions for CM-Series Safety System
CM-Series Safety System
Description:
The CM Series is a tamper resistant non-contact safety
switch system, suitable for use in most types of machine
guarding applications where guard locking is not required.
The system consists of a control unit and 1 or more safety
switches and actuators.
The CM Series non-contact safety switches are easy to
install, tolerant to misalignment and suitable for use in
harsh or wet environments.
The 2-wire connection to each safety switch is
monitored by the control unit, detecting both open
and short circuit faults immediately and returning the
control unit to the off state even if the gate is not
operated.
CM-S41 Control Unit
The CM-S41 is a combined Safety Switch and E-Stop
control unit. Along with the ability to monitor up to four
CM Series safety switches it can also monitor the
normally closed contacts of emergency stop buttons or
mechanical safety switches in dual channel control
circuits. The CM-S41 has 2 normally open safety contact
outputs and 1 normally closed auxiliary output, an
external re-set/proving circuit and LED indication for
‘Power’, ‘Run’ and the status of each activated gate
switch.
CM-S21 Control Unit
The CM-S21 control unit is a 24V ac/dc system that can
monitor up to 2 CM Series safety switches. The CM-S21
has 2 normally open safety contact outputs and 1
normally closed auxiliary output, an external re-
set/proving circuit and LE
D indication for ‘Power’, ‘Run’
and the status of each activated gate switch.
CM-SE Extender Module
The CM-SE Extender module is a 24V ac/dc unit that
can be added to either the CM-S41 or CM-S21 to
monitor an additional 5 CM Series safety switches.
Connection to the main control unit is by a simple 2-wire
bus connection. The status of each guard switch is
shown by the YELLOW LEDs. Additional CMS-E
extender modules can be added to monitor larger
systems.
Safety Switches
The CM Series safety switches are non-contact, tamper
resistant safety switches. Resin encapsulated into an
ABS or Stainless Steel case providing environmental
protection to IP67, the switches can withstand most
conditions including: water, dust and high pressure hose
cleaning.
CM Series safety switches are also available with the
quick disconnect feature.
