voltage. If no, replace the
monitoring device or PSU.
3. Check whether the T/H sensor is
faulty. If yes, replace the sensor.
4. Check whether the
communication between the T/H
sensor and the monitoring device
is abnormal or whether the RS485
cable is damaged. If yes, rectify
the fault.
5. If the fault persists, contact your
dealer or technical support.
1. Check whether the T/H sensor is
faulty. If yes, replace the sensor.
2. Check whether the
communications cable between
the T/H sensor and the
monitoring device is loose,
disconnected, or damaged. If yes,
reconnect the communications
cable.
3. If the fault persists, contact your
dealer or technical support.
1. Check whether the low-voltage
power loop is short-circuited. If
yes, locate and rectify the fault.
2. Check whether overcurrent occurs
in the low-voltage power loop. If
yes, rectify the fault.
3. Rectify the fault before turning on
the switch.
4. If the fault persists, contact your
