Redefining Flow Control
Installation wiring
Route cabling through the most appropriate conduit entry
making sure that cables will not foul on the cover assembly or
internal components after refitting.
Refer to the actuator wiring diagram for connection details.
Terminate the power, control and indication wiring with
appropriate ferrules. Connect wiring to the terminal block
connectors.
Take care to route the wiring away from the spigot housing
on the gearcase.
wARnIng:
The actuator must be checked to ensure that the
voltage specified on the actuator identification
nameplate matches the supply voltage.
CMA is configured at the factory for use with one of the
following power supply voltages:
Note: Supply voltage tol/- 10%. Supply frequency tol/- 10%
Relays
Each relay features Normally Open (N/O) and Normally Closed
(N/C) volt-free contacts. Due to the constraints of the Low
Voltage Directive, the maximum allowable voltage that can be
applied to the relay terminals is 150 VAC. For DC however,
the maximum voltage that can be applied is 30 VDC. Rated
Current is 3A.
CpT feedback
The Loop-powered transmitter provides 4-20 mA signal that
corresponds to position. Loop supply is 24 VDC nominal (20-30
VDC max).
demand
The 4-20 mA command signal is used to control actuator position.
