Troubleshooting
Upon noticing a problem, your first step should almost always be to recalibrate the actuator by toggling DIP
12 while the actuator is powered. This alone can solve basic problems. See sub-section 3 above for more
details.
If the actuator does not move, try following these steps:
1)
Re-calibrate the actuator. This will move the actuator regardless of what signal it is receiving.
2)
A sticking valve may be the problem. Remove the valve from the actuator, and re-test the actuator.
3)
Remove power. Re-check the wiring and the power/signal apparatus. Power actuator and re-calibrate.
If the problem persists, please call Hanbay for technical support.
Battery Fail Safe Function
1. In the event of a loss of power or signal, the battery will maintain power to the P1 processor and
trigger the actuator to move the valve to its designated fail-safe position, using power from the
battery. The digital potentiometer will monitor the position of the valve during this fail-safe operation.
2. Once the valve has reached its fail-safe position, and after about one minute, the P1 processor will
go into sleep mode to preserve the battery life.
3. The actuator will not respond to commands until the power supply is restored.
Note:
The battery will maintain a charge for up to 2 months without power being applied.
The fail-safe actuation can be performed for 30 cycles on the charge available in the battery.
During normal operation, from totally discharged, the batteries will take 2 hours to re-charge.
If in a critical fail-safe application, the battery function should be tested monthly.
Testing Battery Functionality
-
The batteries will be continuously on charge when power is available to the actuator.
-
Regardless of application, the fail-safe function should be tested monthly by signaling the unit to the
position opposite the fail position, removing the power to the actuator and observing whether the
actuator reaches the desired fail position.
-
The battery voltage can be measured with a multimeter set for DC volt measurement.
Measure battery
voltage between the
connector terminals.
Value should be:
7.9 ± 0.4 VDC
