5 Initial setup

5.1 Initialization procedure

Initialization sets automatically the switch points for

the position feedback of the actuator (see fig. 5.2)

Additionally, initialization checks if the actuator

and control module configuration match. This

procedure will detect the action type (Fail-Open,

Fail-Close or Fail in last position) and generate an

alert if there is a configuration issue.

This process is done automatically, by the module,

however, the user must start it and the unit must be

wired according chapter 4.

Digital communication is not required but power

supply is necessary (9V to 32V DC).

The initialization process can be started in one of

two ways:

1. Initialization using the local buttons (see §5.2).

2. Initialization using a bus command (see

Reference manual QC54, DOC.RM.QC54.E)

5.2 Initialization using local buttons

1 Press and confirm press the “Status/Auto-Initial-

ization” button

2 Status LED will blink.

3 Actuator will cycle 2 or 3 times.

4 At the end of the routine the Status LED switches

to constant on, meaning the initialization was

successful.

Remark:

- If the button board does not work, see §5.3.1.

- If the Status LED is flashing, the auto initializa-

tion routine has failed, see §5.3.2.

- If the read out in the PLC or DCS is reversed or

readjustment of the exact positions is needed,

- If it is not possible to finish the auto-initialization

routine, the limit switch points can be set, by the

bus. In both cases, see Reference manual QC54,

DOC.RM.QC54.E. chapter 3.4

WARNING

* During the initialization routine the actuator /

valve combination will cycle several times.

* Before initialization check whether the

actuator and valve have the same “Open” and

“Closed” positions.

* Ensure that the valve stroke is not obstructed

before the initialization routine is started.

5.3.1 “Factory default settings”, using the

button board.

To set the control module to its factory default set-

tings, do the following;

1. Power must be connected according chapter 4

and the Status LED is either on or flashing.

2. Disconnect the power.

3. Press both reassignment (OPEN and CLOSE) but-

tons.

4. Reconnect power.

5. Status LED goes on.

6. Release the reassignment (OPEN and CLOSE)

buttons.

7. Observe that the Status LED indicates that the

unit is in its “Init Default” state (Flashing, see

§5.2)

5.3.2 If auto initialization procedure has failed

(Status LED is flashing)

1. Check supply pressure

2. Check Actuator assembly code (see Installation

& Operation Manual FieldQ Valve Actuator,

DOC.IOM.Q.E)

3. Repeat the initialization procedure.

4. When the actuator does not move within 10

seconds, the auto initialization will fail.

5. To solve this either;

- Perform the “default setting” procedure (see

§5.3.1) and repeat the initialization proce-

dure (see §5.2), or

- Set the limit switch points individually by the

bus see Reference manual QC54,

DOC.RM.QC54.E chapter 3.4.

6 Check functioning

To perform a function test, please see chapter 3 of

Reference manual QC54, DOC.RM.QC54.E.

- After checking the functioning mount the control

module cover to the housing (see figure 3.1).

7 Maintenance

The FieldQ control modules are designed to operate

without maintenance.

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.

8.2 Speed control option

(see figure 8.2).

The FieldQ can be supplied with a Speed Control

option. One throttle is required for Spring Return

actuators and up to two for Double Acting actua-

tors.

The speed control throttle controls the air flow

in and out of an air chamber and as such limits

the speed of the “Opening” and “Closing” stroke

simultaneously

8.2.1 Mounting Speed Control throttle(s):

1. Remove the plug(s) at the side of the module

and turn in the throttle (2).

2. Spring Return actuators: Use the top entry only.

3. Double acting actuators: Use both bottom and

top entries.

- For standard actuators, the top entry will

throttle the closing stroke.

- For standard actuators, the bottom entry will

throttle the opening stroke.

- For reverse acting actuators, the opposite

strokes will be throttled.

8.2.2 Adjusting Speed Control throttle(s):

1. Remove the nut cap (1).

2. Clockwise rotation of the adjustment screw

reduces the speed.

3. Counter clockwise rotation of the adjustment

screw increases the speed.

4. Replace the nut cap.
