Type 5825: Form-Fit Attachment - Samson 5824 Mounting And Operating Instructions

Mounting and start-up
NOTICE
!
Risk of damage to the actuator by turning it
too far.
Only retract the actuator stem as far as the
final travel value.
3. Hold Allen key in place and fasten valve
and actuator together using the coupling
nut (tightening torque 20 Nm). Remove
Allen key and carefully refasten the front
cover.
Retracting the actuator stem electrically
1. Unscrew front cover.
2. Perform electrical wiring according to
Fig. 9 on page 29 and carefully refas-
ten the housing cover.
3. Retract actuator stem:
Switch on power supply and set signal
source to 10 V or 20 mA. The actuator
stem retracts until it reaches the end posi-
tion (torque-dependent limit contact
switches off the motor).
Alternatively, set the operating direction
switch inside the device (see section 8.2)
to increasing/decreasing (<>). In this
case, the input signal must be 0 V or
0 mA.
4. Fasten valve and actuator together using
the coupling nut (tightening torque
20 Nm).
Fail-safe action "actuator stem retracts"
Place the actuator on the valve connection
and tighten coupling nut (tightening torque
20 Nm).
