8.2.4 Behaviour with redundant thermocoupler (TC)
If Red. TC → On/Off → On has been selected, the GUT behaves as follows:
•
If the specified tolerated deviation (max. deviation) is exceeded between the two thermocouples,
− the error signal Err DV RED is output (see section 7)
− a relay with the error signal function drops out (see section 8.5.4)
− a relay with the trip value function (see section 8.5.1) as well as the current output still use the
measured value of the first thermocouple (terminals 1 and 2, see section 6.2) as an input signal
− the current output does not output any fault current
•
If a breakage of one of the two thermocouples has been detected,
− the error signal Err SB or Err SB Red is output (see section 7)
− a relay with the error signal function drops out (see section 8.5.4)
− a relay with the trip value function (see section 8.5.1) and the current output use the measured
value of the non-dropped out thermocouple as an input signal
− the current output does not output any fault current
•
If a breakage of both thermocouples is detected,
− the error signal Err Red is output (see section 7)
− a relay with the error signal function drops out (see section 8.5.4)
− a relay with the trip value function (see section 8.5.1) also drops out unless the Maintain in case
of error function has been selected (see section 8.5.1)
− the current output outputs the selected fault current (see section 8.6.2)
8.2.5 Voltage
The illustration below shows the menu levels subordinate to the Voltage menu item. Menu items of the
lowest menu level are displayed in a bold frame.
If the Voltage sensor type has been selected (On) and you press the OK key, the program guides you
from the Voltage menu item to the Range menu item. If you select again the Voltage sensor type (see
section 8.2.1) and press the OK key twice, the Range menu item is available at once.
Subject to reasonable modifications due to technical advances.
