8 Optional Controls
8.1
Manual Control options
(see figure 8.1)
For commissioning, emergency or maintenance
purposes, the FieldQ can be supplied with one or two
Manual Control options. These can operate the spool
t valve(s) inside the module and as such operate the
actuator, when there is air pressure available, but no
control signal or power supply.
8.1.1 Mounting Manual Control
1. To add a Manual Control, remove the plug(s)
in front of the module and turn in the Manual
Control.
- For normal operation the module should be
fitted with one Manual Control.
- For Double Acting with a Fail-in-Last-Position
function, two Manual Control can be fitted.
8.1.2 Manual Control operation
1. The Manual Control has a “Push & Lock” func-
tion:
- To operate the Manual Control, use a screw
driver, push to activate and release to de-
activate the pilot valves.
- If required turn it 45°, to lock it in position
and keep the actuator in its operated state.
2. In case of a Fail in Last Position configuration
with two manual controls:
- The manual control on the right side (default
location) will pressurize the central air cham-
ber and cause the actuator to rotate counter
clock wise. For reverse acting
FieldQ actuators (Assembly code CC) the
actuator will rotate clock wise.
- The manual control on the left side (Location
for 2nd Manual Control) will pressurize the
end cap air chambers and cause the actuator
to rotate clock wise. For reverse acting
FieldQ actuators (Assembly code CC) the
actuator will rotate counter clock wise.
- In order to operate one of the manual con-
trol, be sure the opposite manual control is
de-activated and unlocked.
