Actuator Wiring
Wiring is dependent on the type of actuator,
mounting, and the desired options that are available.
Consult the actuator model label and then the
relevant sections in the MEP-7500/7800 series
actuators
and
for detailed
1. Loosen (2) wing
nuts and slide
“U” bracket away
from actuators.
2. Depress gear disengagement
button on actuators and rotate
actuators as shown to allow
access to wiring covers.
3. After actuator
wiring is complete,
rotate actuators
back into position,
slide “U” bracket so
that the non-rotation
studs are centered
in rear slot of the
actuator and tighten
the (2) wing nuts.
Dual, Stacked Actuators Wiring Access
instructions on the applicable wiring, feedback
selector, and actuator/signal range reset (auto-
mapping) of the valve’s actuator. For dual, stacked
actuators, follow the process below to access
terminals in both actuators.
CAUTION
Using mineral oil lubricants or other
incompatible substances in system fluids may
damage EPDM rubber seats in valves. Before
using any lubricant or additive in a water or
ethylene glycol base, consult the substance
manufacturer for compatibility with EPDM
(Ethylene Propylene Diene Monomer).
CAUTION
Freeze protection required for fluid
temperatures below 32° F (0° C).
Operation
After the mechanical and electrical installations
have been completed, cycle the actuator to verify the
direction of rotation for normal operation and fail-
safe if so equipped.
