5 Initial setup

FieldQ

October 2018

5.1 Initialization procedure

Initialization sets automatically the switch points for
the position feedback of the actuator (see §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

Before starting the initialization procedure, make
sure the device is in “Out of Service” (OOS). By
default, the device is shipped with the OOS setting.

To set the device to OOS either use the FF system or
a 475 communication tool.

1 Press the Status/Auto-Initialization button for 3

seconds or hold until the LED starts flashing.

2 Press the Status/Auto-Initialization button for 1

second and the LED starts blinking
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

initialization 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,
or

- 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.

6 Check functioning

5.3 Troubleshooting

5.3.1 “Factory default settings”, using the

button board.

To set the control module to its factory default
settings, 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) buttons.

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
procedure (see §5.2), or

- Set the limit switch points individually by the

bus see Reference manual QC54,
DOC.RM.QC54.E chapter 3.4.

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).

11 .3 Safety instruc tions

WARNING

!

• Personal injury or property damage caused
by fire or explosion may occur if the module
is opened in any area which contains a
potentially explosive atmosphere or has been
classified as hazardous.

• The material for the Control Module
housing is an aluminium alloy. When the unit
is used in a potentiality explosive
atmosphere, requiring EPL Ga, the unit must
be installed in such a way, that even in the
event of rare incidents, an ignition source due
to impact or friction between the enclosure
and iron/steel is prevented.

• For applications in explosive atmospheres
caused by air/dust mixtures and where
equipment with EPL Da is required, the
surface temperature has been determined
for a dust layer with a thickness of 5 mm
maximum.

• 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.

12 FISCO Concept

The QC54 module is suitable for use in a FISCO system in accordance with IEC 60079-11 : 2012 for use in
Zone 1 and 2 locations.

12.1 Fieldbus Intrinsically Safe Concept

The FISCO Concept allows the interconnection of intrinsically safe apparatus to associated apparatus not
specifically examined in such combination.

The criterion for such interconnection is that the voltage (Ui or Vmax), the current (Ii or Imax), and the
power (Pi), which intrinsically safe field devices can receive and remain intrinsically safe, considering faults,
must be equal to or greater than the voltage (Uo, Voc), the current (Io, Isc) and the power (Po) levels which
can be delivered by the associated power supply device considering faults and applicable safety factors.
In addition, the maximum unprotected capacitance (Ci) and inductance (Li) of each apparatus (other than
the terminators) connected to the Fieldbus must be less than or equal to 5 nF and 10 µH respectively.

In each I.S. Fieldbus segment only one active device, normally the associated apparatus, is allowed to
provide the necessary energy for the Fieldbus system. The voltage (Uo or Voc) of the associated apparatus,
used to supply the bus, has to be limited to the range of 14VDC to 24VDC.

All other equipment connected to the bus cable has to be passive, meaning that the apparatus is not
allowed to provide energy to the system, except to a leakage current of 50 µA for each connected device.
Separately powered equipment needs a galvanic isolation to insure that the intrinsically safe Fieldbus circuit
remains passive.

12.2 Cable parameters

The cable used to interconnect the devices needs to comply with the following parameters:

Loop resistance Rc: 15 ...150 Ohm/Km
Inductance per unit length Lc: 0.4…1 mH/km
Capacitance per unit length Cc: 80 ...200 nF/km
Cc = Cc line/line + 0.5 Cc line/screen, if both lines are floating or
Cc= Cc line/line + Cc line/screen, if the screen is connected to one line
Length of spur Cable: max. 60 m
Length of trunk cable: max. 1 Km

Length of splice: max. 1

When the cable complies with IEC 60079-11, no further consideration of cable parameters is necessary.
The cable parameters may be determined in accordance with Annex C of IEC 60079-14.

12.3 Terminators

At both ends of the trunk cable, an approved line terminator with the following parameters is suitable:

- R = 90 ...102Ohm

- C = 0 ...2.2 µF

m (T-box must only contain terminal connections
with no energy storage capability)

Note: IEC 61158-2 requires an operational capacitance value of 0,8 µF to 1,2 µF.
The number of passive devices connected to the bus segment is not limited due to I.S. reasons. If the above

rules respected, up to a total length of 1000m (sum of trunk cable and all spur cables), the inductance and
capacitance of the cable will not impair the intrinsic safety of the installation.
