TMS 1
The converter measures a
heating current of less than
300 mA when heater is on.
TMS 2
The converter measures a
heating current of more than
4 A.
TMS 3
TMS temperature sensor
reads a temperature higher
than 139 °C.
TMS 4
TMS temperature sensor
reads a temperature lower
than 1 °C.
Measures
Step 1: Check fuse
Replace fuse TMS (F4A, 5x20 mm) if blown.
Step 2: Check pump (heating element X31)
Check if the connector of the heating element is con-
nected.
The resistance of the heating element X31 is typically
between 70 Ω and 75 Ω. In case abnormal values are
measured contact Leybold service.
Step 3: Check TMS cable
If step 2 was successful do the following:
Check TMS cable for bent pins
Measure resistance between pins X21/AA and X21/q
with the cable connected to the pump. The resistance
is typically between 70 Ω and 75 Ω.
Replace the cable if it is damaged or in case the mea-
surement of the resistance shows abnormal values now.
Contact Leybold service.
Check the line voltage (200-240 V +10% / -15%).
Repeat step 2of failure TMS 1. In case the measured
value is less than 60 Ω contact Leybold service.
Contact Leybold service.
Check TMS sensor
Measure the resistance between pins 1 and 3 of the
TMS temperature sensor. The resistance is typically bet-
ween 110 Ω and 150 Ω (20 °C to 140 °C). Contact
Leybold if the sensor is defective.
Contact Leybold service.
Measure the resistance between pins 1 and 3 of the
TMS temperature sensor. Contact Leybold if the resi-
stance of the sensor is under 100 Ω.
Contact Leybold service.
Possible Cause
Fuse TMS blown.
Heating element or internal
pump connection damaged.
TMS/DRIVE cable or connec-
tors damaged.
Converter failure.
Overvoltage.
Heating element defective.
Converter failure.
TMS sensor damaged.
Converter failure.
TMS sensor short-circuited.
Converter failure.
