D4 Valve with easy-Drive Actuator

November 2013

2. Wait for 10 seconds to ensure all circuits have discharged.

3. Return power to the actuator and use the appropriate calibration method for your control signal. Calibration

sequence must be done within 15 secondsofpowerbeingswitchedon.

4. For On/Off operation using L2e dualinput dry contact:

a. Closethecontacttocreateashortbetweenpins1and2—valveplugwillnotmoveatthistime.

b. Closethecontacttocreateashortbetweenpins1and3—valveplugwillmovetothelower,closedposition.

5. For On/Off operation using single dry contact:

a. Closethecontacttocreateashortbetweenpins1and2—valveplugwillnotmoveatthistime.

b. Open the contact to create an open circuit between pins 1 and 2 — valve plug will move to the lower, closed

position.

6. For positioning operation using 420mA:

a. Apply a 20mA signal between pins 3 and 4 — valve plug will not move at t his time.

b. Apply a 4mA signal between pins 3 and 4 — valve plug will move to the lower, closed position.

c. If calibration of the analog input is desired to improve positional accuracy, an optional operation is listed in the

next section titled Analog Input Calibration.

7. For positioning operation using 15V:

a. Apply a 5V signal between pins 3 and 4 — valve plug will not move at this time.

b. Apply a 1V signal between pins 3 and 4 — valve plug will move to the lower, closed position.

c. If calibration of the analog input is desired to improve positional accuracy, an optional operation is listed in the

next section titled Analog Input Calibration.

8. The unit is now calibrated.

Analog Input Calibration

Improved positional accuracy may be obtained by calibrating the actuator to the analog signal input. The position of

the valve plug is linearly proportional to the analog control signal end points, with 4 mA/1V equating to fully closed

and 20 mA/5V equating to fully open.

1. Apply a 4 mA or 1V signal between pins 3 and 4 - valve plug will move to the fully open position.

2. Send a value of 1 to register 40004 or click Analog Cal at 0% in the configuration software.

3. Apply a 20 mA or 5V signal between pins 3 and 4 - valve plug will move to the fully closed position.

4. Sendavalueof1toregister40005orclickAnalog Cal at 100% in the configuration software.

5. The unit is calibrated to your analog signal.

Start Up

WARNING

To avoid personal injury or property damage, be aware that the valve will move and respond to an input signal during start

up.
