PTC1 Thermal Selection

Program ⇒ Special ⇒ Special Parameters⇒ PTC1 Thermal Selection

This parameter Enables/Disables the optional external thermal detection circuit of the Expansion IO Card Option 1. A thermistor is connected from TH1+ to TH1- of TB3 on the Expansion IO Card Option 1.

Should the thermistor resistance reading fall below 50Ω because of an over- temperature condition or exceed 3000Ω because of an open circuit an External Thermal Fault (OH2) will be incurred.

Direct Access Number — F637

Parameter Type — Selection List

Factory Default — Disabled

Changeable During Run — No

Note: While this parameter is Enabled, the system cannot be restarted until the thermistor value recovers to the level of 1.8kΩ from an over-temperature condition. An Auto-restartwill not be initiated subsequent to an External Thermal Trip (OH2). A manual restart will be required in the event of an OH2 trip.

Settings:

0 — Disabled

1 — Detect Disconnect
