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.

FEATURES:
“Set and Forget” approach 1-9999 dispenses (adjustable) Table top/wall mount
Universal power supply with standard IEC line cord
CSA/UL, CE, RoHS compliant
Learn mode/count to allow customer to command the PDS-100 to “remember” desired dispense cycles needed to fill to a desired volume.
Prime Mode Purge/Reverse Mode
Table-top Mounting: The system is configured for table top installation initially with rubber grommets slid into the mounting slots. Before moving on to configuring the control module, make sure that these rubber grommets are in place. There are no further installation steps for table top use.
Wall-Mounting: For wall mounting, it is necessary to remove the four rubber grommets from the control module before attempting to mount. Each unit must be mounted in the correct orientation; with the labels facing right side up, the control module will have the pumps at the bottom. Wall mounting may require an appropriate mounting board of at least 1/2”(12mm) thickness to straddle the studs of a typical plasterboard wall. See Figure 3.
IMPORTANT When mounting PDS-100 in an enclosure it is important to maintain a minimum clearance to provide adequate space to reach the power switch. See figure 2.

Smooth Flow Operation
The PDS Smooth Flow product differs from the “Standard” PDS-100 in that the dual pumps have each been precisely calibrated to provide equal dispenses per revolution. The distinct difference found in the PDS Smooth Flow is in the method by which the pumps are driven. Proprietary programming provides a unique method of control in such a way as to provide a virtually pulseless output when both pumps are connected to a “Y” or “Tee” fitting.
Most of the controls and screens are the same for the Smooth Flow as shown in the previous pages with the exception that the pumps are not individually controllable. Instead the pumps are controlled as though they are one.
Menus, for the most part, are the same except while in dispense or continuous mode the word “Smooth” will appear at the top of the main screen. In addition you will see the word “Smooth Drive” when power is first applied to the unit.
