Adjusting the counterweight allows you to define the specific water level at which the Tank Full Switch changes state. A typical adjustment procedure is as follows:
Position the float at approximately the desired maximum water level inside the tank.
Slide the counterweight along the cable, moving it closer to or farther away from the float until it is in the desired position. The position of the counterweight determines how much force the float must apply to activate the internal mechanism.
Slowly fill the tank and observe the point at which the switch changes state.
Adjust the counterweight along the cable, moving it closer to or farther away from the float, until the activation level (when the internal switch is activated) matches the desired water level.
Once the correct level is reached, make sure the counterweight is securely fixed to prevent it from moving due to motion or vibration.
Practical tips
- Small adjustments can result in significant changes to the switching level, so move the counterweight in small steps.
- If the switch activates too early (before the desired water level is reached), move the counterweight closer to the float.
- If the switch activates too late (after the desired water level is exceeded), move the counterweight farther away from the float.
