Overview

Overview

System Description

Each tandem supply system consists of two air-powered rams; both of which are always the same size. Each ram drives a Check-Mate pump and a platen into a drum of material. The pump removes material from the drum and pushes it through a supply hose to a customer-sup­plied header. Material flows through the header to indi­vidual dispense drops.
When one drum is emptied the system performs an automatic crossover, shutting off the air supply to the pump on the empty ram and activating the pump on the full ram.
Keep clear of the inactive ram, as automatic crossover may occur unexpectedly. To repair or adjust the ram, first follow all steps of the Pressure Relief Procedure on page 22.

Ram Installation and Setup

Fluid Filter Kit Installation

Some systems include a fluid filter kit. See Appendix A
- User Interface Display on page 31. Ensure that the
fluid filter stand base is level in all directions. If neces­sary, level the base using metal shims. Secure the base to the floor using anchors that are long enough to pre­vent the filter stand from tipping.
1. Connect pressure sensor cable from the fluid filter kit to port 7 of the fluid control module.
2. Connect male side of the splitter to the other end of the pressure sensor cable.
3. Connect end of splitter cable labeled #1 to the pres­sure sensor on the outlet side of the filter.
4. Connect end of splitter cable labeled #2 to the pres­sure sensor on the inlet side of the filter.
1. Install and set up individual rams as explained in manual 313526 (supplied).
NOTE: See F
IG. 2 on page 13 (for pneumatic crossover sys-
tems) and F systems) for examples.
2. Connect pneumatic line (AC) or CAN cable (X) between rams.

Overview

Grounding

The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.
Pump: use ground wire and clamp (supplied). Loosen grounding lug locknut and washer. Insert ground wire end into lug slot and tighten locknut securely. Connect ground clamp to a true earth ground.
Air and fluid hoses: use only electrically conductive hoses with a maximum of 500 ft. (150 m) combined hose length to ensure grounding continuity. Check elec­trical resistance of hoses. If total resistance to ground exceeds 29 megohms, replace hose immediately.
Air compressor: follow manufacturer’s recommenda­tions.
Dispense valve: ground through connection to a prop-
erly grounded fluid hose and pump.
Exhaust port with muffler (BD)
Air motor regulator (BE): Controls air pressure to
motor.
Air motor slider valve (BF): turns air on and off to the air motor. When closed, the valve relieves air trapped between it and the air motor. Push the valve in to shutoff. Remote DataTrak: The air solenoid (Y, F
IG. 2), the air motor slider valve (BF), and the
main air slider valve (BA) must be open for air to flow. (See Remote DataTrak Setup section in Supply Systems operation manual 313526.)

Fluid supply container: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive sur­face, such as paper or cardboard, which interrupts grounding continuity.
To maintain grounding continuity when flushing or relieving pressure: hold metal part of the dispense
valve firmly to the side of a grounded metal pail, then trigger the valve.

Integrated Air Controls

The integrated air controls include:
Main air slider valve (BA): turns air on and off to the system. When closed, the valve relieves pres­sure downstream.
Ram air regulator (BB): controls ram up and down pressure and blowoff pressure.
Ram director valve (BC): controls ram direction.

Pneumatic Crossover System Components

NOTE: D200, D60, and S20 sizes are used in pneumatic crossover systems.
F
IG. 2. shows a pneumatic crossover system. Refer to
manual 313526 (supplied) for ram installation and oper­ating instructions. The pneumatic crossover operates as follows:
During system operation, as the ram approaches the drum bottom, the top of the ram contacts the limit switch (E). The limit switch shuts off air to the air motor via a solenoid valve (Y), which stops air flow to one motor and starts air flow to the other air motor. This allows continu­ous material flow and changing of material drums.
The position of the limit switch (E) on the ram deter­mines when the air motor is turned off. Start by position­ing the limit switch to trip when the ram platen (D) is 1 in. (25 mm) from the bottom of the drum. During operation the position may be adjusted as desired.
The bypass valve (L) allows you to prime the inactive pump after a drum change. Open the valve to prime the pump. Close the valve when priming is complete, and during normal operation.

Overview

Electronic Crossover System Components

NOTE: D200 and D60 sizes are used in electronic crossover systems. See F you should be familiar with the following compo­nents.
NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures.
Both rams (A and B) include a Check-Mate Pump (C), platen (D), integrated air controls (H), drum empty sen­sor (E), and fluid control module (G).
Only Ram A includes the display module (F) and power supply box (K).
Drum empty sensor (E). Signals drum empty condition.
Display module (F). Mounted on Ram A only. Provides Run Mode status screens, Setup screens, and control keys.
Fluid control module (G). See page 21.
IG. 3. Before you install the system,
Integrated air controls (H). See page 11.
Power supply box (K).
Air motor solenoid (Y). Solenoid is on when system is on and in Run Mode, Recirculate Mode, or Prime Mode. Solenoid is off when system is shut off or when in Depressurize Mode, or the ram is in an Inactive Ready Mode. Turns on in Recirculate Mode. The solenoid LED will illuminate when the solenoid is on.
Depressurize/recirculate fluid valve (Z). Depressurizes system when Depressurize Mode is active. Recirculates fluid when Recirculate Mode is active.
To depressurize the system, press the Depressurize
key on the display module and select Yes when
asked if you want to depressurize the system. Follow the Pressure Relief Procedure on page 22. Shutting off power or removing power from the system will not depressurize the system.
