DESCRIPTION
The CM Series safety system 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 comprises 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.
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 LED 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 LED's.
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.
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.
