Carrier 17/19EX - Manual (Page 87)

Automatic Restart After a Power Failure is not activated when a power failure occurs, and the
remote contact is closed, the machine will indicate an alarm because of the loss of voltage.
The contacts for Remote Start are wired into the starter at terminal strip TB5, terminals 8A
and 8B. See the certified drawings for further details on contact ratings. The contacts must be
dry (no power).
Spare Safety Inputs
Normally closed (NC) digital inputs for additional field-supplied safeties may be wired to the
spare protective limits input channel in place of the factory installed jumper. (Wire multiple
inputs in series.) The opening of any contact will result in a safety shutdown and LID display.
Refer to the certified drawings for safety contact ratings.
Analog temperature sensors may also be added to the options modules, if installed. These
may be programmed to cause an alert on the CCN network, but will not shut the machine down.
Spare Alarm Contacts
Two spare sets of alarm contacts are provided within the starter. The contact ratings are
provided in the certified drawings. The contacts are located on terminal strip TB6, terminals 5A
and 5B, and terminals 5C and 5D.
