• Use DIP switch 1 to select static mode or pulse counter mode.
• Disconnect the device from the supply voltage.
• Switch the supply voltage back on.
• The selected mode is now active.
7.5.4 Functions in pulse counter mode
The counter state can only increase consecutively. When the maximum counter limit of
4294967295 is reached, the counter state is automatically reset to 0.
There are also three ways to reset the counter state manually:
Via power up
• Disconnect the device power supply and then reconnect the voltage.
Via Modbus/RTU register
• Reset the counter states via Modbus/RTU as follows:
– DI1: bit 0 = 1 (register 40xx1)
– DI7: bit 1 = 1 (register 40xx1)
By setting the inputs
• Set the corresponding input for at least 0.5 seconds:
–Set input DI3 in order to reset counter state DI1.
–Set input DI5 in order to reset counter state DI7.
