Function: Thermostat Fault (Setting:87)
<0032>
A digital input can be configured to indicate a Thermostat Fault from an external contact (H1-0x = 87). An open contact into the multi-
function input will enable the Thermostat Fault. After an initiation of a Thermostat Fault to disable the Thermostat Fault requires a closed
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.
