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: 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. Table 5.1 Status LED indications Status Status LED action OK (init successful) Initializing Init error Init default Identification Constant on Blinking (see fig. 5.1) Flashing (see fig. 5.1) Flashing (see fig. 5.1) Flashing for 300 sec. 1.

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 Bettis Q-Series 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.BQC54.E chapter 3.4. Check functioning To perform a function test, please see chapter 3 of Reference manual QC54, DOC.RM.BQC54.E. - After checking the functioning mount the control module cover to the housing (see figure 3.1). 7 Maintenance The Bettis Q-Series control modules are designed to operate without maintenance.

These can operate the spool 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. Location for 2nd Manual Control 1. The Manual Control has a “Push & Lock” function: - 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 chamber and cause the actuator to rotate counter clock wise. For reverse acting Bettis Q-Series actuators (Assembly code CC) the actuator will rotate clockwise. - - 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 Bettis Q-Series actuators (Assembly code CC) the actuator will rotate counter clock wise. In order to operate one of the manual control, be sure the opposite manual control is de-activated and unlocked. 45° On Default location of Manual Control Off Fig. 8.1 Local Manual Control options 9 Bettis Q-Series Installation guide October 2018 DOC.IG.BQC54.1 Rev. 3 9.1 8.2 Speed control option (see figure 8.2). The Bettis Q-Series can be sup- plied with a Speed Control option. One throttle is required for Spring Return actuators and up to two for Double Acting actuators. 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.

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 m (T-box must only contain terminal connections Length of splice: max. 1 with no energy storage capability) 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 C = = 90 ...102Ohm 0 ...2.2 µF 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. 17 Bettis Q-Series October 2018 18 Installation guide DOC.IG.BQC54.1 Rev. 3 Installation guide DOC.IG.BQC54.1 Rev. 3 Bettis Q-Series October 2018 19 World Area Conﬁguration Centers (WACC) offer sales support, service, inventory and commissioning to our global customers.
