Connect the resistor 680 Ω
or 820 Ω (or a jumper),
between terminals 26 and 27.
Can C-alarm be reset
manually?
Channel D
Connect an ammeter to
terminals 31 and 32 (NOTE!
Correct polarity ±).Depress
switch 58. The instrument
shall now indicate the set
alarm level (from factory,
set to 100° C (212°F), which
corresponds to 10 mA).
For test of the channel D-alarm
function, the instrument
shall indicate 7 – 14 mA.
Adjust if necessary with
potentiometer 60.
Turn off the supply current.
Disconnect the sensor from
terminals 28, 29 (and 30).
Connect a jumper between
29 and 30. Connect a resistor
130 Ω between terminals
28 and 29. Turn the supply
current back on. Does the
instrument indicate about
5.5 mA?
Turn off the supply current.
Substitute a 150 Ω resistor
for the 130 Ω resistor. Turn the
supply current on. Does the
instrument indicate about
16 mA?
Is D-alarm activated and
cannot be reset?
