Each of the two Control Ports on the module has a 2 input signals: Local Accumulation and Infeed/Discharge Interlock. Each of these inputs has a default logical state (on or off) that enables the function. The Control Port Inputs area contains check boxes to invert the logical state of these inputs to accommodate your particular needs. Please note that these checkboxes are for Left and Right ports on the module and not the logical Upstream or Downstream zones
| By default, the module interprets the Infeed/Discharge input signal (Interlock Pin 4 on RJ-12 Control Port or P4 on a SE-4) when energized or ON to mean a logical “1”. By clicking the check box to invert the Infeed/Discharge input signal, a de-energized or “OFF” condition will mean a logical “1” to the module for the Interlock Pin 4 Control Port signal |  |
| By default, the module interprets the Accumulation input signal (Pin 3 on RJ-12 Control Port or P3 on a SE-4) when energized or ON to mean a logical “1”. By clicking the check box to invert the Accumulation input signal, a de-energized or “OFF” condition will mean a logical “1” to the module for the Pin 3 Control Port signal |  |
