CM-SE CONNECTIONS
POWER SUPPLY :
24Vac/dc
POWER SUPPLY FUSING :
Internal resetable fuse with 2 second delay after
fault removal.
INDICATION :
RED - Power On.
YELLOW - guard status indicators.
GUARD SELECTION :
See CM-SE Guard selection chart.
CONNECTION TO MAIN CONTROL UNIT:
The CM-SE can be connected to any active guard
switch input on an CM-S21 or CM-S41.
Connect the 2-wire BUS ( BL DR ) terminals on the
CM-SE module to any activated guard input on the
main control module. (Max distance 100 metres)
For larger systems further CM-SE extender
modules can be connected to active guard switch
inputs on an CM-SE extender module.
OPERATION :
When power is applied to the control module, the RED 'Power Led' will illuminate. The number of inputs selected must match
the number of guard switches, more or less and the control unit will not operate. The YELLOW 'Guard status' indicators will be
illuminated if the guard is closed or be permanently on if the guard is de-selected.
If all the monitored machine guards are closed and the RE-SET button is pressed and released on the main control unit, the
control relays will energize and the normally open safety contacts on terminals 13,14 / 23,24 (main control unit) will close. The
normally closed auxiliary contact 31 & 32 (main control unit) will open. If set to automatic re-set ( i.e. link in X1 & X2) the
control relays will energize when all active guards are closed and the emergency stop button(s) (if connected) are re-set.
Faults on the safety switch cables, either open or short circuit will be detected immediately causing the control relays to de-
energize.
