■ Components
- Open the cover and insert the cable into the inlet.
- Find the contact cable (E1, E2 ...) that you want and connect it.
- Install an electrical spring connector and then use a tool to press it.
■ Terminal Block (Opt.)
- Open the cover and insert the cable into the inlet.
- Check the contact identification of the terminal block (E1, E2 …) and connect it.

Maintenance
■ Take out the product from the container and open the cover.
■ Release the cable gland and then cut the cable tie. Try not to cause damage to th
e cable or guide wire while cutting the cable tie.
■ Adjust the cable as you want under the flange.
■ Tighten the cable gland to seal the container.
■ If the cable is too long, cut it appropriately and then connect it.
■ Tie the cable with a guide wire using a cable tie. Keep it at about 100 mm away fr
om the float or the float will not work.
The float and switches are important parts to be inspected for the HQ-Series. Their service
lives depend on the user environment and they can be optimized with regular inspection.
As such, users are advised to conduct regular inspection and maintenance at least every y
ear.
Conduct a visual inspection to find any damaged float or disconnected cable. If you find a
scale used to measure the subject, remove it to facilitate the floating motion. The switche
s can be checked using a digital multimeter as follows.
- Set the switch of digital multimeter to the buzzer. To check, connect it to a cable termi
nal.
- It is normal for the buzzer to make a sound when the float is tilted at 90˚ or more fro
m its vertical position.
- To check the contact with resistance, set the digital multimeter switch to Ω. Then, tilt th
e float to see if it is normal: if the digital multimeter indicates a 0Ω or a ∞ with the fl
oat on or off, respectively, it means that it is working fine.
For maintenance, make sure the power supply to the product has been cut off.
4-SPST/2-SPDT
※ 3-SPDT or higher is restricted for an 8P terminal block, so connect it to
contact A or B according to requirements.
