Operating modes
The software-driven menu facility on the unit allows the user to configure the unit to monitor the belt speed according to the user’s parameters. The unit works in one of two modes:
1) Static mode.
2) Dynamic mode.

1) Static mode
In static mode, the device only monitors whether the belt is running above the user defined run-speed or not. If the belt speed falls below the run-speed, the potential-free contact will be de-energized.
A 4-20 mA signal given to the PLC at all times.

2) Dynamic mode
In dynamic mode, the device is used in conjunction with the conveyor’s switch gear. An output from the main contactor is wired to the unit’s drive input. When the drive starts up, the drive input to the unit is energized and the unit goes into moving mode. The display will read the actual speed and the PLC can be updated via the 4-20 mA output from the controller.

Analog output
The  4-20mA output increases in steps of 250uA per 0.1m/s increase in measured speed, which results in a 20mA output at a speed of 6.4m/s
