Use - commissioningMaintenanceSepam comprises self-testing and self-diagnosisto facilitate installation maintenance.Indicator lamps and displaymessagesc Green indicator lamp lit up Sepam is energized.c No indicator lamps lit upThere is probably an auxiliary power supply fault.Check the auxiliary power supply and connections tothe CE40 board. Perform the lamp test.c Red lamp indicates internal Sepam faults.Sepam continuously performs on-line internal tests.When the test results are negative, Sepamautomatically runs a series of sequences which resultin either:v automatic reinitialization (minor fault, e.g. transientauxiliary power supply break).Sepam carries out a complete restart sequence. Ifrestart is successful, Sepam operates again normally.All the output relays arede-energized (1) ,v switching to the fail-safe position. All the outputrelays drop out (1) in order to avoid inadvertentcommands, and the watchdog drops out as well.The following may cause internal faults:c Missing cartridge:v red indicator lamp lit up,v display OFF,v no dialogue with TSM2001 pocket terminal,v no dialogue with communication link,v watchdog dropped out,v switching to fail-safe position.Sepam 2000 will not start, lacking a program: this is amajor fault,c Configuration fault:v red indicator lamp lit up,v red lamp indicates CARTRIDGE,v no dialogue with the TSM2001 pocket terminal,v no dialogue with the communication link,v the watchdog is dropped out,v switching to fail-safe position.Sepam 2000 is shut down: this is a major fault.v The type of cartridge is not compatible with theSepam model.Caution: do not insert or remove the cartridgewhile Sepam is energized.v Disconnect the auxiliary power supply and wait 2seconds before handling the cartridge.Check the references on the Sepam and on thecartridge (refer to chapter on Sepam identification).v Sepam is automatically disabled until theappropriate cartridge is installed.c Other major faults:v red indicator lit up,v display indicates MAINTENANCE or CARTRIDGE,v no dialogue with the TSM2001 pocket terminal,v no dialogue with the communication link (if the CPU is faulty),v the watchdog is dropped out,v switching to the fail-safe position.Sepam 2000 is shut down: this is a major fault.Consult your maintenance department.c Minor or partial fault:v red indicator extinguished,v display indicates MAINTENANCE or CARTRIDGE,v dialogue with the TSM2001 pocket terminal is maintained,v dialogue with the communication link is maintained,v the watchdog does not drop out.Sepam 2000 is operating, however it has detected a transient fault or one of thecomponents has failed to pass self-testing.Consult your maintenance department.Communication indicator lampsThese lamps are located at the rear of the device on the CE40 module when themodule is equipped with the communication option.c Green indicator lamp blinking: indicates traffic on the line.This is the normal operating mode.c Indicator lamps extinguished: There is no communication.Check the cabling and inquiries at the level above.c Red indicator lamp lit:indicates initialization of the coupler, which lasts about 2 seconds, or a couplerfault.Consult your maintenance department.c Red indicator lamp lit up and the recommendations given in the maintenancechapter do not allow Sepam to be restarted.Call in the maintenance department.c CONNECTORv Indication that one or more connectors are unplugged.Check that the connectors are plugged in and tightened by screws on the rear ofthe device.Check that the DPC has been strapped on all the connectors.(1)this may cause tripping with undervoltage control logic ("fail-safe" logic).Use - commissioning2/13
