Directional and flow control valves“COMNICA”
• COMINCA valves offer independent setting for acceleration and deceleration which is indispensable for shockless operation. High speed positioning which is difficult with conventional shockless valves and adjustable speed setting is possible.• Onboard microprocessor allows setting of required parameters without valve to valve variation. Push button operation while monitoring the integrated digital indicator enables simple, repeatable setting and adjustment. Handheld setting device provides same setting operation as on the valve.
• Compact, space-saving design with same configuration and robust construction as standard solenoid valves. Ease-of-use design facilitates operation as well as installation and maintenance with features such as operation confirmation when valve is deenergized, manual override pins, and reduced wiring.• Like standard solenoid valves, can be connected to general purpose relays, PLC’s, etc.

Operating Considerations
1. Mounting orientationValve should be mounted with spool axis orientedhorizontally.
2. T portAbnormal surge pressures in T port should be kept tobelow 13.7 MPa. Valve should always be filled with oil.
3. Signal lineEnds of signal wires not used should be insulatedand short circuits should be prevented.
4. Wiring specificationsWhen using extended lead wires for COMNICA valves,insure that cables are heat and oil resistant and ofproper size as described below.• Power supply (24V or 0V) AWG18 or above 0.75mm2
• Contact point signal or analog input AWG22 or above 0.3mm2
5. Contact point input-output currentWhen contact signal is input, the following currentsflow to the contact points of the PLC, relay, etc. Careshould be paid to the current limitations of externaldevices.Setting point current (A) (contact point inputvoltage -1)/15000Operation output (CH type only) max. load current is50mA and care should be paid to the load on thePLC, relay, etc. Especially when connecting directlyto LED, etc., serially connect resistance to operationaloutput + or operational output -, and limit current.Minimum applicable load ( )‚ (load voltage-1.2)/0.05
6. Manual operationValve can be manually shifted by pushing the manualoverride pins but force required will increase as tankline back pressure increases.
7. Water and dust protection classWater and dust protection class is IP54. Separateprotection should be implemented for jets from nozzles,etc. In order to maintain water and dust resistance,nameplate and packing should be tightened with the
tap pins after adjustment of settings. Tighteningtorque: 0.34 ~ 0.53Nm
8. EMI (electro-magnetic interference)Valve control flow may vary with changes in themagnetic field.As shown in the examples below, when flow iscontrolled by solenoid “a” and a nearby solenoid valveis energized, controlled flow of the COMNICA valvemay increase or decrease as shown in the table.Therefore caution should be exercised when COMNICAvalves are operated in proximity to solenoid valves

Shockless (SH) Type
Operation
Wiring (Example)
Two - high/low speed - flow levels, high/low speed arrival times, and low speed flow hold time can be independently set for solenoids “a” and “b”.Shockless operation and speed control (flow control) can be easily obtained by selecting the A (solenoid ‘a’) or B (solenoid ‘b’) direction withthe contact point signals of the sequencer. Also positioning control can be obtained by using the stop signal (HALT). (When the energizesignal to the solenoid is cut, mode automatically switches to low speed.)
If stop (HALT) signal is input, COMNICA valve will stop according to deceleration time TOA or TOB setting.

Operation
Wiring (Example)
Three flow levels - high speed, medium speed, low speed - and arrival times for solenoids “a” and “b” can be independentlyset. Valve can be directly connected to sequencers, general-purpose relays, proximity switches, etc., to provide simplemanagement of shockless operation, speed control (flow control) and positioning.
Input of emergency stop signal, will immediately generate zero output from amp to valve regardless of whether there are other contact pointinput signals and valve returns to neutral position and zero flow. Valve return time to neutral position will be the minimum time of the valveregardless of the TOA and TOB setting times.Operational output signal will be ON (contact point closed) when controller is operating normally and OFF (contact point open) underabnormal conditions and during data setting. Operational condition can be viewed with the monitor.
*1 Source method wiring possible. Reverse polarity of inputcommon for source method.* 2 When using shielded cables, connect shield cable to FG(ground earth) or OV.

Operation
Analog Input (AN )Type
Wiring (Example)
Operation is based on direction of analog voltage polarity with absolute values specified for flow. By setting lag timein advance, ramping can be achieved in response to step input. Lag time is set by arrival time against max. flow. ‘A’direction ramp up time (TAU), ramp down time (TAD), ‘B’ direction ramp up time (TBU) and ramp down time (TBD)can be set separately.
Input of emergency stop signal, will immediately generate zero output from amp to valve regardless of commandvoltage and valve returns to neutral position with zero flow. Time of valve return to neutral position will be theminimum time of the valve regardless of the TAD and TBD setting times.

Handheld Setting Device
Model: COH-1-10 (for all COMNICA valves)
• Handheld setting device allows easy data setting ofCOMNICA valves in difficult locations.• Contact point signal name and flow setting valuesselected during operation can monitored similar as withthe valve display.
• COMNICA valve basic data can be copied to thehandheld setting device and copied into other COMNICAvalves enabling same settings for multiple valves.
� In addition as shown in the illus-tration at right, the device can alsobe used as a converter when aPC is used to set data for theCOMNICA valve. As a result,by using a PC, various adjust-ment values can be copied tomultiple COMNICA valves assettings. (integrated RS-232C/422 converter function)
