ME cylinder lubrication malfunction cylinder #nn
ALM−20 No. LED On / Off Code
Indication #01 to #09 Fail Red Two times each
interval
Cause A cable is broken between an ALM−20 (plug X1, terminals 13 and 14) and the pressure trans-
mitter (PT3131C to PT3139C).
Procedure ⇒ Do a check of the cables on the related ALM−20. If the cables are serviceable, the pressure
transmitter has a malfunction
⇒ Make sure that the related cable connections between ALM−20 (plug X1, terminals 13 and 14)
and pressure transmitter are connected correctly and have no damage.
⇒ If necessary, repair or replace damaged cables.
⇒ If necessary, replace the related pressure transmitter (PT3131C to PT3139C) if necessary

ALM−20 No. LED On / Off Code
Indication #01 to #09 Power Off None
Cause No power supply to an ALM−20
Procedure ⇒ In E85, do a check of the power supply units U500 / U501 and their circuit breakers F500 /
F501
⇒ If a green LED DC OK shows, do a check of the cables on the related ALM−20 (plug X2,
terminals 21 and 22 or 23 and 24)
⇒ If a green LED DC OK flashes, do a check of the cables on the related ALM−20 and/or the
related ALM−20 (do a check for a short circuit)
