3. Mounting
3.1 General mounting instructions
1. Fit the emergency stop actuator in non-actuated condition by means
of the ELM mounting flange, align and tighten (max. 0.6 Nm)
2. Snap the EFR.1 or EFR spring elements in the middle position of the
ELM mounting flange (position 3).
3. The EMERGENCY STOP actuator is latched (i.e. mechanically fixed)
to the EFR 1 or EFR spring element by actuation. Unlatching by pulling
on the EMERGENCY STOP actuator retentions the spring element
and the EMERGENCY STOP is brought back to the ready position.
4. Snap the desired EF... contact elements onto the free positions to
the right and to the left (position 1 and 2) next to the EFR.1 or EFR
spring element.
5. Mounting of the securing plate with the EFR (not required with the EFR.1):
Installation of EFR discontinued for NDRZ... emergency
stop devices. Instead of the ELM mounting flange, the EFM
mounting flange is installed here. The relevant mounting
flange is included in the items supplied with the device head.
If using NDRZ... emergency stop devices with the PS116
position switch, the supplied EFM mounting flange must be
replaced with the EFMH mounting flange.
For position switch combinations, secure the position switch
to the EFMH mounting flange using the supplied screws and
tighten to a torque of 0.8 Nm. The washers are not required
for the PS116 position switch and have been left out.
The pre-mounted assembly group from EFMH and the
position switches are now mounted on the emergency stop
control panel in an unactuated state, aligned and screwed
tightly (max. 0.6 Nm).
