PDS-100

Programmable Dispensing System

INSTRUCTION MANUAL

OVERVIEW

The PDS-100 is a precision system capable of

dispensing or pumping fluids ranging from 5 uL per

dispense or 15 uL/min continuous (Single RH00LF) up

to 1536 mL/min (Dual Q3) into pressures ranging from

10 psi (Q3) to 100 psi (RH). The PDS-100 offers

single, dual (in phase, out of phase and independent)

pump head control. PDS-100 offers RS485

communications, which allows the user to control the

PDS-100 via a PC or PLC. Dry contact inputs offer an

easy method to start and stop the pumps through the

use of a simple switch. The PDS-100 also offers inputs

which provide control of the dispense rate via a 0 – 10

VDC, 0 –5 VDC or 4–20 mA input.

A simple easy to use local keypad provides the user

access to local control of the pump or pumps and a

vivid display to provide user-friendly menus for ease of

control.

Configuration Modes Screens (Appears when Up Arrow and setup Keys are held down while powering up unit) The unit comes pre-configured as a Dual Individual system when purchased as a dual pump system. To configure the dual pump system for “In Phase” operation or “Out Phase” operation follow the procedure mentioned above to modify. If the unit supplied is a single pump system there is no need to change the configuration. Possible drive configurations types supported (configured by factory): 1. * 2. 3. 4.
