Safety Interlock Switches
CM Series CM
Description
The CM series of controllers and coded magnetic switches
offers the most flexibility and widest range of options available.
The CM series is comprised of two basic technologies.
Controller Technologies
2-Wire Single Channel Controllers
The CM-S41 and CM-S21 controllers monitor the 2-wire
magnetically coded switches. The CM-S41 and CM-S21 control-
lers use a patented technology which allows them to monitor the
2-wire or single channel switches up to Category 3. The ability to
monitor just a single channel enables the CM-S41 and CM-S21 to
easily monitor multiple switches and provide individual status of
each channel. Both of these controllers are compatible with the
CM-SE expansion module.
Dual Channel Controllers
The CM-S4 and CM-S30 controllers are designed to monitor
conventional read-style, magnetically-coded switches with 1 N/O
+ 1 N/C contacts. The CM-S4 controller can monitor up to four
switches to category 3. The CM-S4 controller offers status indica-
tion for each individual switch. The CM-S30 controller can monitor
one switch to category 4, or two switches to category 3. The CM-
S30 control unit is capable of monitoring up to 30 conventional
read style switches in series, but does not conform to category 3
when used with more than two switches.
Switch Categories
The CM series of switches are all magnetically coded.
The CM series of switches fall into three main categories:
1. 2-wire Coded Magnetic
2. Conventional Read Style 1 N/C + 1 N/O contacts
3. Universal Read Style 2 N/C + 1 N/O contacts
The 2-wire Coded Magnetic Switches are only compatible with
the CM-S21, CM-S41 and CM-SE control units and expansion
module. The Conventional Read Style Switches are compatible
with the CM-S4 and CM-S30 controllers. The Universal Read
Style Switches are unique in design, all three contacts are rated
for safety. This means that Universal Read Style switches can
be used with the CM-S4 or CM-S30 Controllers, or conventional
safety monitoring relays such as the G9SA, SR103 or G9SX-AD,
-BC. This allows the Universal Read Style Switches to be run in
series with E-stop switches or other mechanical door switches.
Typically a category 2 rating would be applied to a system that
incorporates multiple switches wired in series to a standard safety
monitoring relay. A risk assessment should always be performed
by properly trained and authorized personnel.

CM Series Safety Interlock Switches
2-Wire Single Channel Controllers
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, 2-wire 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 reset/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 24 VAC/DC system that can moni-
tor 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 reset/proving circuit
and LED indication for “Power”, “Run” and the status of each
activated gate switch.
CM-SE Extender Module
The CM-SE expansion module is a 24 VAC/DC unit that can be
added to either the CM-S41 or CM-S21 to monitor an additional
5 CM Series safety swtiches. 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
modules can be added to monitor larger systems.

Dual Channel Controllers
CM-S4 Control Unit
The CM-S4 controller is capable of monitoring up to four,
magnetically coded switches with 1 N/O + 1 N/C contacts up to
category 3 according to EN954-1. The CM-S4 has a dedicated
dual channel input for each switch and has LED status indicators
for each channel. The CM-S4 has 1 N/O safety contact and 1 N/C
Aux contact. External Device Monitoring (EDM) is available using
Y1,Y2 inputs.
CM-S30 Control Unit
The CM-S30 controller is capable of monitoring one magneti-
cally coded switch with 1 N/O + 1 N/C contacts up to category
4, or two switches to category 3 according to ISO 13489-1. The
CM-S30 control unit is capable of monitoring up to 30 convention-
al read style switches in series, but does not conform to category
3 when used with more than two switches. The CM-S30 controller
has 2 N/O safety contacts and 1 N/C Auxillary contact. External
Device Monitoring (EDM) is available using Y1,Y2 inputs.
