TERMINAL CONNECTIONS
Connect the unit as in the diagram below.
Attach the CJC sensor together with input wiring to the
input terminals. The CJC sensor is not interchangeable.
Check that its serial number is identical to that of the unit.

CHECKING
Open the unit’s outdoor enclosure cover when you conduct
checking of the transmitter. Be sure to close the cover after
the checking is complete.
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Input: Check that the input voltage is within 0 – 100% of
full-scale.
If the thermocouple or its extension wires are broken, the
output goes over 100% (below 0% with downscale) due to
burnout function. Check leadwires in such a case.
3) Output: Check that the load is within the permissible
limit including wiring resistance.
Load Resistance (Ω) =
Supply Voltage (V) – 13 (V)
0.02 (A)
(including leadwire resistance)
