5 Assembly 5.1 General notes
Actuators NK and VK, Position Controller ESR-NK 27
−
Only use original accessories from Agromatic Regelungstechnik GmbH
for the actuator.
NOTE
Risk of damaging the actuator!
Improper handling may cause the control shaft of the actuator to be bent.
The control cams installed on the control shaft actuate the limit switches
and the auxiliary switches. Therefore, any modification to the distance
between the shaft and the switches will cause the switching points to be
shifted.
For this reason:
–
Do not use the control shaft to lift the actuator.
–
Do not apply lateral forces or impact-like forces on the control shaft.
–
Do not use the control shaft to rotate the actuator.
Please note the following when installing couplings (not included in
scope of delivery):
−
Do not use force to rotate the output shaft.
−
The output shaft of the actuator and the valve shaft must run centrically! If
this is not the case, a suitable coupling may be used to compensate any
unbalance.
