The control unit must not be mounted inside the hazard zone. Access to the control unit is required for
manual reset or for routine indicator observation so it must be able to be seen operating. The control
unit can be mounted on either side of power doors, as long as the only hazard is the actual doors.
In all other cases the control unit can be mounted anywhere convenient outside the hazard zone,
taking into account the access requirements for test and maintenance.

4.6 Reset terminal MC-MC

These terminals are used for a number of different functions (surface mount supplied jumpered,
DIN rail supplied without jumper). Without the jumper the terminals can be connected to positively
guided normally closed auxiliary contacts on the machine contactors to provide monitoring of the
contactors in dual channel control systems. If one contactor fails to isolate the power at
de-energisation of its control coil, the Safedge system will not allow the other contactor to be
energised until the fault has been rectified. Fit a jumper between these terminals on the DIN rail
unit if this function is not required.This terminal is also used for auto/manual reset. If the MC-MC
terminal is left jumpered or connected up to the contactors normally closed contact only, the unit
is in automatic reset mode. In automatic reset mode the output is achieved solely by removal of
the actuating force. The out put is also achieved at power up of the actuator (when there is no
actuation force present). If a spontaneous restart may generate a risk, based on the result of a
risk assessment to EN1050, then this mode must not be used. See EN 60204 Pt.1 and EN954
Pt.1. For manual reset mode a normally open spring return (not latching) push button must be
connected across the MC-MC terminals or in series with the contactors normally closed. When
the actuating force is removed, the unit will not operate until the button is pressed. The button
will also have to be pressed after power up of the control unit.

4.7 Profile connection to control units

These terminals are used to connect the Profile to the:-

Z1 = Brown (inner conductor).
Z2 = White (outer connector).

Refer to 5.3 APPLICATIONS.
NOTE: Profile must be terminated with a 6K

Ω Resistor (yellow) for series connection. When two

profiles are connected directly to Z1 and Z2 (parallel) then each profile should be terminated with
a 15K resistor (blue).

Connection in Parallel & Series

ALTERNATIVE CONNECTION METHOD

CONNECTING IN PARALLEL

A maximum of two profiles can be connected in parallel to
assist in ease of wiring in certain applications.

Uses 15K resistor (blue)

CONNECTING IN SERIES

If more than one profile is to be used they are normally connected
in series as shown.

Uses 6K8 resistor (yellow)
