Latching interface background
The LVD Control Interface (LCI) translates the L-ADIO control relay state change into a fixed duration high current
pulse to the contactor, thus preventing the contactor coil from being continuously powered in case of operator or
controller error. It does this by charging a capacitor in the pulse generator when a control relay is off, and then
discharging it when the control relay is on. Therefore, it is necessary to have the control relay off for a short time
period (< 1 second) between actuation attempts. This recharging is done through the Normally Closed contacts
of the control relay on the L-ADIO.
Troubleshooting
Symptom Possible cause
Manual operation does not work Check if related LED is illuminated, if not check the
L-ADIO connection.
Contactor closes after manual opening Check Cordex HP controller function, is it
reconnecting due to high battery voltage? If so
unplug K6.
Contactor opens after manual closing Check Cordex HP controller function, is it
disconnecting due to low battery voltage? If so
unplug K5.
Contactor won’t operate and the green LED on LCI
Board is not illuminated
Check if battery or rectifier output is live.
Contactor won’t operate but the green LED on LCI
Board is illuminated
Check if the battery is disconnected. (If the rectifier
output is live the load bus will power the green LED.)
Power LED simply provides the status that either one of these sources is present.
