6 Safety manual 53
9 If active, deactivate SIL operation of the test piece.
Configure test piece for connection to the thermocouple sensor type, NiCr-Ni, type
'K', internal cold junction, and configure analog output to current signal (4 mA to
20 mA; error signal: negative signaling).
Connect current meter between connection 54(+) and 51(-) and measure the cur-
rent. No current must be measurable (~0 µA). Verification that the power
source is switched off for the
RTD temperature probe in the
thermocouple configuration.
10 Connect short-circuit jumper between connection 52(+) and connection 51(-).
Check whether the temperature displayed by the display corresponds to the ambi-
ent temperature with a deviation of ± 5 °C. Verification of proper function of
the acquisition of the cold junc-
tion temperature for thermocou-
ples.
11 Configure test piece for connection to the double thermocouple sensor type, NiCr-
Ni, type 'K', internal cold junction, and configure analog output to current signal
(4 mA to 20 mA; error signal: negative signaling).
Test the resistance between the following connections with an ohmmeter:
53 to 51: display < 5
Ω
Verification of proper function
for the second thermocouple.
12 Switch off test piece and connect current meter using a burden of 500
Ω
between
connections 42(+) and 41(-).
Switch on test piece and configure analog output for simulation of current output
signal 21.2 mA. The output signal acquired using the current meter must be
21.18 mA to 21.22 mA. Configure analog output for simulation of current output
signal 3.6 mA. The output signal acquired using the current meter must be
3.59 mA to 3.61 mA.
Verification that the output driv-
er stage of the analog output
can drive the maximum admissi-
ble burden.
