5 Commissioning

In order to commission the QC40 ASI Control
Module, the following actions must be considered
or done:

1 Re-adjustment of the limit switch points if the

factory setting do not meet the application
requirements

2 Addressing of the QC40 ASI Control Module

5.1 Re-adjustment of the limit switch points

5.1.1 Factory switch point settings

Mechanical stroke: 90°±0.5° (Actuator setting)

Switch points: ± 15° before each end of

Adjustable range: -20° to +3° at each end.

5.1.2 Before re-adjusting the limit switch points

IMPORTANT

* Before mounting the actuator on the valve, be

sure that both the actuator and the valve have
the same “open” or “closed” position.

* Set the Mechanical stroke before setting the

limit switches.

5.1.3 Pneumatic and electrical connections

Make pneumatic and electrical connections before
adjusting the limit switch setting.
See chapter 3 and 4.

5.1.4 Switch point setting and valve
rotation direction.

The QC40 ASI Control Module is equipped with
non-intrusive switch point adjustment. The
adjustment screws are accessible behind a shield in
the front of the module (see Figure 5.2).

This means that the switch point adjustment can be
done without opening the module.

Normally valves are “Closed” after a
clock wise rotation.

- In this case the top adjustment screw

(see Figure. 5.2), sets the switch point of the
“Closed” position and bottom adjustment screw
sets the switch point of the “Open” position.

- For a valve that is “Open” after a clock wise

rotation, the position feedback will be reversed.

The Table below indicates which re-adjustment
screw is related to the “Open” or “Closed” switch
point setting.

If required the mechanical stroke and the limit
switch setting can be re-adjusted.

- For mechanical stroke adjustment of the actuator,
please see document DOC.IOM.Q.E, available
from www.emerson.com/fieldq.

- For re-adjusting the limit switches,
see procedure below.

5.1.5 Working principles Switch Operating

Mechanism (see Figure 5.2)

The Switch Operating Mechanism is intend to
operate the position feedback switches and allows
adjustment of the switch points in the open and
closed end positions. Factory setting is that the
switches are activated 15° before the end of the
open and closed stroke.

Switch Operation

The rotation of the actuators pinion operates the
IPT device (1) which results in a linear movement.
The linear movement of the IPT device operates
lever (3). The lever amplifies the linear movement
of the IPT device and operates the switch operating
rod (5). Dowel pin (6) in the rod operated the levers
of the open and closed switch elements (8 & 9).

8

6

7

5

The lever is of the “floating” type. When the IPT
device operates the lever, it moves completely
upwards until it meets the upper pivot block (4). At
this point the lever will tip over and pull down the
switch operating rod (5) and operates the
bottom switch (7). When the IPT device moves
back the springs cause the lever to move
completely downwards until it meets the lower
pivot block (2). At this point the lever will tip over
and push up the switch operating rod (5) and
operates the top switch (8).

Switch point adjustment

The position of the lower pivot block (2) can be
changed by adjustment screw (10) and the position
of the upper pivot block (4) can be changed by
adjustment screw (9).

By adjusting the position of these pivot blocks the
switch points will be changed.

The adjustment screws (9 & 10) can be found
behind the shield (12) in front of the module. To
access the adjustment screws loosen the screw (11)
and rotate the shield (12) as shown.

5.1.6 Re-adjustment of switch points

IMPORTANT

The procedure below assumes:

- That the actuator and control modules are

according the factory settings.

- If th e switch setting is somehow lost or forgotten,

then consult paragraph 6.3 to set the switch point
setting back to factory setting.

- That the actuator / valve assembly is closed

after a clock wise rotation (see chapter 5.1.4).

Below procedure assures that the position feedback
complies more accurately with the valve position
and will set the switch point at approximately 4°
before the end of the stroke.

To set and detect the Open or Closed switch points,
the QC40 AS-I module has two LED’s that light
up if the Open or Closed position limit switch is
activated.

Procedure (see Figure 5.3):

1. Loosen the screw (1) of the shield (2) and turn
the shield down.

Closed Position:

2. Send an “Close” command to the ASI module,
wait and make sure the valve has moved to
closed position.

3. Turn top screw (3) counter clock wise (do not
force the adjustment screw) until the switch
trips and the corresponding LED (5) goes out.

4. Turn top screw (3) clock wise (do not force the
adjustment screw) until the switch trips and
the corresponding LED (5) goes on. This position
represents the actual, mechanical “closed”
position of the valve.

5. Turn the screw minimal a 1/2 turn clock wise.
The “closed” position switch point is now set.

Open Position:

5. Send an “Open” command to the ASI module,
wait and make sure the valve has moved to
open position.

6. Turn bottom screw (4) clock wise (do not force
the adjustment screw) until the switch trips
and the corresponding LED (6) goes out.

7. Turn bottom screw (4) counterclockwise

(do not force the adjustment screw) until the
switch trips and the corresponding LED (6) goes
on. This position represents the actual “open”
position of the valve.

8. Turn the screw minimal a 1/2 turn counter clock
wise. The “open” position switch point is now set.

9. Turn the shield (2) back over the adjustment
screws and fasten it with the screw (1).

Important:

During switch point adjustment, do not force the
adjustment screws when you feel an obstruction.
Forcing the adjustment screws can damage the
cross head of the adjustment screw.

6 Trouble shooting

6.1 The “Open” and “Closed” position
feedback signals are reversed from the
actual valve positions.

1 Check if the actuator is correctly mounted to

the valve.
Before mounting the actuator on the valve, the
actuator and the valve should have the same
“open” or ‘closed” position (see Installation &

Operation Manual FieldQ Valve
Actuator DOC.IOM.Q.E).

2 Some valves may be operated in such a way that

they are:

- “Open” after a clock wise rotation and

- “Closed” after a clock wise rotation.

3 Please see § 5.1 for setting the “Open” and

“Closed” position feedback signals

6.2 The actuator does not give (good)
position feedback signals.

1 Check if the actuator is correctly mounted to

the valve.

2 Re-adjust the limit switch setting as per

chapter § 5.1

6.3 Factory setting of the switch points.

IMPORTANT

The procedure below assumes:

- That the actuator / valve assembly is closed

after a clock wise rotation (see also § 5.1).

- The control module is pneumatically and

electrically connected according
chapter 3 and 4.

This procedure sets the switch point settings of the
switches, back to the factory settings (±15° before
each end of stroke), assuming a mechanical stroke
of 90°±0.5° of the actuator.

To set and detect the Open or Closed switch points,
the QC40 AS-I module has two LED’s that light
up if the Open or Closed position limit switch is
activated.

must be done in safe area’s without a
potential explosion hazard.

• Installation, adjustment, putting into service,
use, assembly, disassembly and maintenance
or repair, shall be carried out in accordance
with the applicable code of practice by
suitably-trained personnel.

• Provisions must be made to prevent the
rated supply voltage being exceeded by
more than 40%.

• Potential electrostatic charging hazard, clean
only with a damp cloth - danger of
propagating discharge.

• The apparatus shall be installed in such a way
that the risk from electrostatic discharges
and propagating brush discharges caused by
rapid flow of dust is avoided.

• Precaution shall be taken to avoid danger of
ignition due to electrostatic charges on the
marking plate of the enclosure.

• Substitution of electronics cartridge, switch
cartridge, pilot valve cartridge, pneumatic
cartridge, enclosure and seals must be with
parts from Emerson else the suitability for
Division 2 will be impaired.

11.4 CSA safety instructions

22 with ammable dusts, bres and yings in
groups IIIA, IIB and IIC, with a layer auto­ignition temperature of not less than 75 K
above the maximum surface temperature
marked in the dust coding.

• There are no special checking or maintenance

conditions other than a periodic check.

• With regard to explosion safety, it is not

necessary to check for correct operation.

• If the equipment is likely to come into contact

with aggressive substances, e.g. acidic liquids
or gases that may attack metals or solvents
that may affect polymeric materials, then it is
the responsibility of the user to take
suitable precautions that prevent it from
being adversely affected thus ensuring that
the type of protection is not compromised.
