OVER-TEMP WARN
Closed when the control heat sink detector senses the control is within
3 Deg C of tripping on INT OVER-TEMP.
MOTOR DIRECTION
Closed when reverse input direction command is received, open for
forward.
Opto-isolated Inputs
Nine Opto-isolated inputs are available at terminals J1-8 through J1-16 to command various output
conditions. The available command input may change depending on the operating mode selected.
Opto-isolated Input Power
The opto-isolated inputs (J1 connector pins 8-16) are normally operated by closing contacts or
switches between them and pin J1-17, input common. The voltage rating of the opto inputs is 10-30
VDC. The opto inputs may be configured as sinking or sourcing provided all of the inputs are
configured the same.
See Figure 2-16 below for opto-input power configuration options.
NOTE:
IF THE CONTROL'S INTERNAL 24VDC SUPPLY IS TO BE USED TO POWER
THE OPTO INPUTS, CONNECTOR PIN J1-39 MUST BE JUMPERED TO
J1-40 AND ALL RETURNS TERMINATED AT J1-17.
