4.10 Malfunction of Cylinder Lubrication
LEDs on the ALM−20 show malfunctions and defects of the cylinder lubrication
control system (see Fig. 2). Data about irregular functions with the lubricating pump
components, or in the lubricating and servo oil system are given in 0820−1,
paragraph 2 Cylinder lubrication.
Failure text ME cylinder lubrication malfunction cylinder #nn (ID 2.6)
ALM−20 No.
LED Blink intervals Failure ID Display
Indication #01 to #09 Pressure Yellow None 126 2.6
Cause No pulse lubrication. The cylinder lubricating system has a malfunction, which activates a
slow-down signal.
Procedure ⇒ Do a check of the cables to the pressure transmitter, 4/2-way solenoid valve and WECS−9520
for correct connections and / or damage.
⇒ Find the cause of the malfunction of the ALM−20.
⇒ Do a check for low servo oil pressure, or no servo oil pressure.
⇒ If the servo oil pressure is correct, do a check of the lubrication pump components (see
0820−1, paragraph 2 Cylinder lubrication).
⇒ Make sure that the cables to the pressure transmitter, 4/2-way solenoid valve and
WECS−9520 are correctly connected and have no damage.
⇒ If necessary, repair or replace damaged cables.
⇒ If necessary, replace he related ALM−20, or lubrication pump components (see 0820−1, para-
graph 2 Cylinder lubrication).
Failure text Cylinder LUB Malfunction (ID 2.8)
ALM− No. LED Blink intervals Failure ID Display
Indication #01 to #09 Pressure Yellow None 128 2.8
Cause No pulse lubrication. The cylinder lubricating pumps have a malfunction, which activates a
slow-down signal.
Procedure ⇒ Do a check of the cables to the pressure transmitter, 4/2-way solenoid valve and WECS−9520
for correct connections and / or damage.
⇒ Find the cause of the malfunction of the ALM−20.
⇒ Do a check for low servo oil pressure, or no servo oil pressure.
⇒ If the servo oil pressure is correct, do a check of the lubrication pump components (see
0820−1 paragraph 2, Cylinder lubrication).
⇒ If necessary, repair or replace damaged cables.
⇒ Make sure that the cables to pressure transmitter, 4/2-way solenoid valve and WECS−9520
are correctly connected and have no damage.
⇒ If necessary, replace he related ALM−20, or lubrication pump components (see 0820−1,
paragraph 2, Cylinder lubrication).
