5 Display of the operating states
The two LEDs “Power“ and “Status“ provide information about the current operating status of the
EPE2-Controller for Meter Draining System.
 After switching on the power supply the yellow “Power“ LED lights briefly and then goes off
for approx. 1s. Then it has to light up continuously.
 If an error was determined during initialisation, the corresponding flashing error code is emit-
ted (see Table 3: Display of the operating states with LED’s below).
 In “Stand-Alone residue discharge“ mode (DIP switch S1-2 “OFF“ on the power supply
board SVC-2S) the green “Status“ LED shows the current switch status of the solenoid
valve and the flow computer switching relay.
 If the green “Status“ LED lights continuously then the solenoid valve is powered and the
flow computer switching relay has engaged.
 If a product shortage is detected, the green “Status“ LED starts flashing for the time interval
T1. The solenoid valve is now de-energised and switched off.
 If time T1 is elapsed the green “Status“ LED goes off, the switching relay is now also de-
energised and thus switches off the supply voltage of the flow computer.
