DESCRIPTION

Models equipped with remote inputs and outputs can be controlled by external signals connected at the rear panel 9-pin

"D" shell connector. The Remote inputs permit control of the pump by remote equipment or accessories. Figure 2

shows the signal locations of the connector.

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.
