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.
