Sensor details
Discharge gas tem-
PTC sensor switching at 140 °C.
perature sensor: Resistance range 20 - 100 Ω at 15 - 50°C (value for each sensor).
Functioning principle: only slight change in resistance when heated up
below the switching point temperature, but in the switching point range
the resistance value suddenly changes by several kOhm.
Oil temperature sensor: Sensor KTY84-130 (see diagram: resistance temperature curve)
Functioning principle: resistance value changes according to the
change in oil temperature
Differential pressure switch:
∆P Reed contact, IP 65
Switching current: 30 mA, switching power: max.
30 VA; Ambient temperature: -30 … +70°C

All the errors saved in BCM 2000 (up to 170) incl. the operating hours counter total can be read out
with a PC, the reading program on CD-ROM and the cable. In addition, the following trigger settings
can be changed on the spot depending on the prevailing conditions:
Out-of-step: Compressor blocked after every standart shut-down: 180 s
Variable time range: 0 - 255 s
For rack operation, set this position to “0” or hide with bypass switch 7,
see pos. 7 in the chapter “error messages – information messages –
emergency operation.
Oil pressure error time: Shut-down delay (standart setting): 90 s
Variable time range: 15 - 90 s
Rotation detection: Vibration factor (standart setting): 2
Variable time range: 0 - 40
