Mounting and
Installation
All A-Series industrial electric actuators are suitable for direct mounting on Siemens
resilient seat butterfly valves.
NOTE:
The standard mounting position for the actuator is to orient the base of the actuator
parallel to the pipeline.
To mount an actuator on a vertical pipe, position the unit with the conduit entries
on the bottom to prevent condensation from entering the actuator through its
conduits.
Use a “liquid tight” conduit connector to maintain NEMA 6P rating.
Service
The resilient seat butterfly valve and actuator are maintenance-free.
Wiring
CAUTION:
When wiring an A-Series Industrial Electric Actuator for two-position
(on/off) control and the power to the actuator is commanded to be off, you
must ensure that there is no extraneous or leakage voltage between hot
and common. Leakage voltage greater than 3 Vac can cause actuator
failure.
When wiring an A-Series Industrial Electric Actuator for two-position
control, the controller should use at minimum a one-second time delay for
command signal reversal. Instantaneous command reversals may cause
actuator failure.
Figure 1.. On/Off.
NOTE:
Use this A-Series Industrial Electric Actuator only to control equipment under normal operating conditions. Where
failure or malfunction of the electric actuator could lead to personal injury or property damage to the controlled
equipment or other property, additional precautions must be designed into the control system. Incorporate and
maintain other devices such as supervisory or alarm systems or safety or limit controls intended to warn of, or
protect against, failure or malfunction of the electric actuator.
