F35403 — TM: Temperature fault/alarm threshold channel 7 exceeded

F35403 is raised by the temperature evaluation of channel 7 on the Terminal Module 150 (TM150): either the alarm threshold of the channel (p4102[14]) has been exceeded for longer than the delay time set in the timer p4103[7], or the fault threshold (p4102[15]) has been exceeded. This fault only causes the drive to shut down if there is at least one BICO interconnection between the drive and the Terminal Module. Without such an interconnection the fault does not shut the drive down. Depending on how the drive is configured, the same threshold condition can also be issued only as an alarm or with no reaction at all.

• The alarm threshold of channel 7 (p4102[14]) has been exceeded for longer than the time set in timer p4103[7].
• The fault threshold of channel 7 (p4102[15]) has been exceeded.

1. Allow the temperature sensor of channel 7 to cool down until its temperature lies below the fault threshold p4102[15] minus the hysteresis p4118[7].
2. Check the measured sensor resistance in r4101[7] together with the resulting temperature in r4105[7]: for sensor type PTC thermistor or Bimetallic NC contact (p4100[7] = 1, 4), the drive sets r4105[7] to 250 °C when r4101[7] is above 1650 ohms and to -50 °C when it is 1650 ohms or less.
3. If required, set the fault response of this fault to NONE using p2100 and p2101.

• The fault value in r0949, interpreted decimal, contains the temperature actual value of channel 7 at the time the fault was initiated, scaled in 0.1 °C.
• The current temperature actual value of the channel is output via connector output r4105[7] and can be interconnected.
• For sensor type PTC thermistor or Bimetallic NC contact (p4100[7] = 1, 4): r4105[7] shows 250 °C when r4101[7] is above 1650 ohms, and -50 °C when r4101[7] is 1650 ohms or less.

• p4102 — index [14] holds the alarm threshold and index [15] the fault threshold of channel 7; the temperature must fall back below these values.
• p4103 — timer p4103[7] sets how long channel 7 may stay above its alarm threshold before the fault is initiated.
• p4100 — sensor type of channel 7; the values 1 and 4 select the PTC thermistor and the Bimetallic NC contact behaviour.
• p4118 — hysteresis p4118[7]; the sensor must cool to below the fault threshold p4102[15] reduced by this hysteresis.
• p2100 / p2101 — used together to change the fault response for this fault number, for example to NONE, if required.
• r4101 — shows the resistance of the channel 7 sensor, which for PTC and bimetallic sensors is judged against 1650 ohms.
• r4105 — connector output with the channel 7 temperature actual value; it can be interconnected in the drive.
• r0949 — fault value; for F35403 interpret it decimal as the temperature present at initiation, in 0.1 °C.

The fault is acknowledged immediately; a POWER ON also clears it. Before the drive is restarted, the sensor must have cooled down to below the fault threshold p4102[15] minus the hysteresis p4118[7], as the remedy specifies.
