REMOTE INPUTS

The FRONT PANEL/REMOTE switch enables remote functions. Switching to FRONT PANEL disables the remote
functions, allowing the front panel controls to operate the pump.
When the FRONT PANEL/REMOTE switch is in the REMOTE position, starting and stopping the pump is controlled by
an external contact closure between pins 6 and 7 (Jumper B), and the pump speed is determined by an externally
supplied 2–10 V or 4–20 mA source. Connection must be made between pins 6 and 7 and a control voltage greater than
2 V or a control current greater than 4 mA must be applied for the pump to run.
If setting the speed from the front panel is desired with remote Start/Stop contact operation, the FRONT PANEL/
REMOTE must again be in the REMOTE position. In addition, Jumper A should be in place. Jumper A connects pin 5
of the "D" shell connector (REMOTE/LOCAL SPEED) to pin 6 (RETURN). Start/Stop will then be controlled from the
rear panel (Jumper B), and the pump speed will be controlled from the front panel. The accessory Footswitch (part no.
73-750-000) and Dispenser Wand (part no. 73-055-590) are connected internally in this way.
Figure 3 shows four typical wiring configurations: 2–10 V follower, 4–20 mA follower, accessory dispenser wand (or
footswitch), and full front panel control.
NOTE: The signal common for the speed control voltage and current inputs is referenced to earth ground.
The table Operation Summary for the Feature Inputs summarizes the remote input operation.
