Select a surge absorber that satisfies the following conditions.

Wiring Auxiliary Outputs (1, 2, and 3)

• On the 900-TC8, Auxiliary Output 1 (SUB1) is output across terminals

9 and 10, Auxiliary Output 2 (SUB2) is output across terminals 7 and 8,
and Auxiliary Output 3 (SUB3) is output across terminals 5 and 6.

• When the HBA or the HS Auxiliary is used with the 900-TC8,

Auxiliaries are output across terminals 9 and 10.

• On the 900-TC8, when heating/cooling control is used, Auxiliary

Output 3 becomes control output (cooling).

• On the 900-TC16, Auxiliary Output 1 (SUB1) is output across terminals

7 and 8, and Auxiliary Output 2 (SUB2) is output across terminals 6
and 8.

• On the 900-TC32, Auxiliary Output 1 (SUB1) is output across terminals

5 and 6.

• On the 900-TC32, when heating/cooling control is used, auxiliary

output 1 becomes control output (cooling).

• When the HB, the HS, or heater overcurrent alarm is used with the

900-TC16, alarms are output across terminals 7 and 8.

• On the 900-TC16, when heating/cooling control is used, Auxiliary

Output 2 becomes control output (cooling).

• When the Input Error Output parameter is configured to ON, the

output assigned to Alarm Output 1 turns ON when an input error
occurs.

• For models that have a Heater Burnout Alarm (not supported by

900-TC32), an OR of the alarm 1 function and the HB/HS or heater
overcurrent alarm is sent to the output assigned to the alarm 1 function
(auxiliary output 1). If ALM1 is to be used for HBA only, configured the
Alarm 1 type to 0 and do not use Alarm function 1.

• The following diagrams show the internal equalizing circuits for Alarm

Outputs 1, 2, and 3.
