A35907 (F, N) TM: Hardware initialization error
Drive object: DCP_CTRL, TM150, TM15DI_DO, TM31
Cause: The Terminal Module was not successfully initialized.
Alarm value (r2124, interpret hexadecimal):
01: TM17 or TM41 - incorrect configuration request.
02: TM17 or TM41 - programming not successful.
04: TM17 or TM41 - invalid time stamp
Remedy: Carry out a POWER ON.
A35910 (F, N) TM: Module overtemperature
Drive object: DCP_CTRL, TM150, TM15DI_DO, TM31
Cause: The temperature in the module has exceeded the highest permissible limit.
Remedy: - reduce the ambient temperature.
- replace the Terminal Module.
A35911 (F, N) TM: Clock synchronous operation sign-of-life missing
Drive object: DCP_CTRL, TM150, TM15DI_DO, TM31
Cause: The maximum permissible number of errors in the master sign-of-life (clock synchronous operation) has been
exceeded in cyclic operation.
When the alarm is output, the module outputs are reset up to the next synchronization.
Remedy: - check the physical bus configuration (terminating resistor, shielding, etc.).
- check the interconnection of the master sign-of-life (r4201 via p0915).
- check whether the master correctly sends the sign-of-life (e.g. set up a trace with r4201.12 ... r4201.15 and trigger
signal r4301.9).
- check the bus and master for utilization level (e.g. bus cycle time Tdp was set too short).
A35920 (F, N) TM: Error temperature sensor channel 0
Drive object: DCP_CTRL, TM150, TM15DI_DO, TM31
Cause: When evaluating the temperature sensor, an error occurred.
Alarm value (r2124, interpret decimal):
1: Wire breakage or sensor not connected.
KTY84: R > 1630 Ohm (TM150: R > 2170 Ohm), PT100: R > 194 Ohm, PT1000: R > 1944 Ohm
2: Measured resistance too low.
PTC thermistor: R < 20 Ohm, KTY84: R < 50 Ohm (TM150: R < 180 Ohm), PT100: R < 60 Ohm, PT1000: R < 603
Ohm
Remedy: - make sure that the sensor is connected correctly.
- replace the sensor.
A35921 (F, N) TM: Error temperature sensor channel 1
Drive object: DCP_CTRL, TM150
Cause: When evaluating the temperature sensor, an error occurred.
Alarm value (r2124, interpret decimal):
1: Wire breakage or sensor not connected.
KTY84: R > 1630 Ohm (TM150: R > 2170 Ohm), PT100: R > 194 Ohm, PT1000: R > 1944 Ohm
2: Measured resistance too low.
PTC thermistor: R < 20 Ohm, KTY84: R < 50 Ohm (TM150: R < 180 Ohm), PT100: R < 60 Ohm, PT1000: R < 603
Ohm
Remedy: - make sure that the sensor is connected correctly.
- replace the sensor.
