Auxiliary Thermocouple Input Connector (J15)
Thermocouple wires are to be connected to pins 4 and 5 on Connector
J15
. No connections are to be
made to pins 1, 2 and 3 on connector
J15
.
NOTE: Both the
Auxiliary
and
Main
thermocouples must be of the same type: E, J, or K. Refer to the
instructions on the previous page (B-21) for connector
J9
to set the thermocouple type for both the
Auxiliary
and
Main
thermocouples.
Polarity Type “E” Type “J” Type “K”
J15 - Pin 4 (+) Chromel (purple) Iron (white) Chromel (yellow)
J15- Pin 5 (-) Constantan (red) Constantan (red) Almel (red)
If the
Auxiliary
thermocouple is not wired correctly on Pins 4 and 5 of
J15
, or the thermocouple is
damaged, there will not be any error message on the Control and the temperature displayed will remain
at approximately ambient room temperature.
Temperature Analog Output Connector (J10)
Connector
J10
provides analog output signals proportional to the temperatures of the
Main
and
Auxiliary
thermocouples. The temperature of the
Main
thermocouple is present on
J10
Pin 3. The temperature of
the
Auxiliary
thermocouple is present on
J10
Pin 2.
