Enable PIB
Green - Enable signal from PIB OK
Blinking Green/Red - Software
deactive and
Enable Chain - HW OK.
Blinking Red during start up -
Waiting for loading of FPGA.
Off - Enable signal lost
Blinking Red - Failure – Check communication cable from PIB to Main
Computer.
– Check communication cable to SIB and MIB.
Enable SIB
Green - Enable signal from PIB
OK. Communication between SIB
and PIB is OK.
Off - Communication lost.
Blinking Red - Failure – Check communication cable from SIB to PIB.
– Check Power LED on SIB.
Enable MIB
Green - Communication between
MIB and SIB is OK (MIB OK).
Off - Communication lost.
Blinking Red - Failure – Check communication cable from MIB to SIB.
– Check Power LED on MIB.
Enable Manipulator 1
Green - OK. MCOB is operative.
Blinking Red - Failure, MCOB not
ready.
Indicator lights red during purging
sequence. Enable signal from MCOB or robot temp. sensor chain.
– Check Temp. Motors LED.
– If used, check working area limit switches for
manipulator axes, wiring and connectors.
– If used, check collision protection, wiring and
connectors.
Enable Manipulator 2
Same as Enable Manipulator 1 but
for 2nd manipulator such as CBS.
2 Ch. Monitoring
Green - OK.
Blinking Red - Failure, divergency
in switches and/or relays in safety
chain. – Check Run Chain LEDs for divergency.
– Check safety chain switches and relays for malfunction.
– Check wiring and connections for Emy Stop buttons.
– Safety element not tested after divergency failure.
Power Status
Green - OK.
Blinking Green - Low voltage on
measuring system battery.
Blinking Red - One or more supply
voltages faulty, e.g. emy stop chain
supply. If LED is blinking green,
– Replace the battery.
If LED is blinking red,
– Check 24V supply to PDB.
– Check PDB power status LEDs
– Check Purging status.
– Check Fuses for rectifier (DC Link).
– Emy stop chain supply.
Temp Cabinet
Green - OK.
Blinking Red - Temperature in
control cabinet or transformer too
high. – Check cause of increased temperature in cabinet. Take
necessary measures to reduce temperature. (By
excessive ambient temperature cooler may be
installed).
– Check PTC on mains transformer and wiring.
Enable Chain Closed
Green - OK. Enable chain is active.
Blinking Red - Chain is not active. The ‘Enable Chain Closed’ LED indicates that all elements
in the enable chain are active.
– Check that all SYSTEM LEDs above the ‘Enable Chain.
Closed’ LED are OK. If not, correct error as required.
