Function: Thermostat Fault (Setting: 83)
A digital input can be configured to indicate a Thermostat Fault from an external contact (H1-0x = 83). A contact closure into the multi-
function input will enable the Thermostat Fault. After an initiation of a Thermostat Fault, to disable the Thermostat Fault requires a open
digital input contact, the drive run command to be open and reset the Thermostat Fault via the drive's reset button or fault reset input.
Note: An OPE12 fault will occur if H1-xx = 83 and 87. H1-xx cannot be programmed to “83” and “87” at the same time.

Function: Disable Pre-Charge (Setting: 84)
A digital input can be configured to enable or disable the Pre-Charge function (H1-0x = 84). A contact closure into the multi-function
digital input will disable the Pre-Charge function independent of the value programmed into the Pre-Charge Time (P4-03). When the
digital input is open, the Pre-Charge function is enabled.
