form, the high-level report is normally open, and the low-level report is normally closed. For the DTDP form, the
high-level report is normally open-common-side, low-reported normally-closed-common.

3. All terminals should be in good contact, the output nut should be properly pressed to prevent the lead from
loosening.
4. Make sure the wiring port is pointing vertically downwards. Make sure that the extra wires do not interfere with
the movement of the switch cover or switch mechanism.
7.3 Debugging Process
7.3.1 Ordinary float level controller, lift or lower the float to simulate level lift before installation, and use a
multimeter to verify whether the output status is correct (Figure 8 output status is empty can state).
7.3.2 Self-checking float level controller, use multimeter to verify whether the output status is correct. Under the
empty tank state, simulate the high level and pull the self-test handle downward. Then use the multimeter to
check whether the signal is switched once, then pull up. Dynamically simulate a low level and use a multimeter to
check if the output is correct. Note that the position of the handle must be placed at the working position after
commissioning (see Figure 9)
