Operational Verification

WARNING
To avoid personal injury or property damage, be aware that the valve will move and respond to an input signal during start
up.
1. Before turning on power to the unit, be sure that a closed signal is being commanded to the unit.
D Single Dry­Contact: contact is open.
D Dual Dry Contact: Contact closed across pins COMMON and CLOSE.
D Analog Input: signal = 4 mA.
D Modbus: position demand = 0.
2. Turn on power to the unit.
3. Apply a change in position demand to ensure unit responds properly.
D Single Dry­Contact:
H Closed contact between pins COMMON and OPEN will open the valve.
H Dual dry contact: Closed contact between pins COMMON and OPEN will open the valve. Closed contact
between pins COMMON and CLOSE will close the valve.
D Analog Input: valve will respond to proportional demand.
D Modbus: valve will respond to positional demand in register 40001. 0 = fully closed and 1000 = fully open.
4. If the valve does not respond as expected, proceed to Troubleshooting guide of this instruction manual.
5. Check conduit ports
D Conduit seal must be in place within 450 mm (18 in) of the enclosure.
D Unused conduit ports must be sealed with an explosion-proof port plug.
6. Replace the cover and tighten all 10 bolts to 40.7 N•m (30 ft•lbs).

Troubleshooting

1. Unit does not move.
a. Green heartbeat LED will pulse near Modbus terminals when power is present. Verify the 12VDC to 24VDC is
present on the power terminals as shown on the cover.
b. Verify all wires are firmly attached on both ends, screw terminals are fully screwed down and wire gauge is
sufficient for length of wiring.
c. Verify the wires are connected to the correct terminals - see Wiring in the manual.
d. Verify the configured control method matches control signal.
e. Verify the configured valve type matches the mounted valve.
