AVOID LOCATIONS WHERE THE DLC-XP/RC WOULD BE SUBJECTED TO EXTREME COLD OR

HEAT

[LESS THAN -18° CELSIUS (0° FAHRENHEIT) OR GREATER THAN 40° CELSIUS (104°

FAHRENHEIT)] OR DIRECT SUNLIGHT. FAILURE TO OBSERVE THIS WARNING COULD DAMAGE

THE

DLC-XP/RC AND VOID ITS WARRANTY.

5.2 Installation Notes

1. The DLC-RC is a microprocessor based controller that uses static sensitive CMOS components. Do

not make any electrical connections (high or low voltage) without adequately grounding the DLC-RC

and the worker to eliminate an electro-static charge between the two. A conductive wrist strap worn

by the worker and attached to the DLC-RC enclosure is adequate to satisfy this requirement.

2. Calibration is an important element of successful DLC-XP/RC operation, the permanent installation

of a calibration column as shown in Figure 1 is strongly recommended.

3. Conduit connections can carry fluids and vapors into the DLC-XP/RC causing damage and void of

warranty. Care should be taken when installing conduit to protect against fluid/vapor entry. Sealed

fittings within 18 inches are required for all connections to the DLC-XP.

4. The upper enclosure cover of the DLC-XP pump-mounted control unit must be securely and

properly fastened to ensure compliance with hazardous area regulations. See Section 6.1.2 for

the proper procedure.

5.2.1 Electrical Wiring

The DLC-XP/RC has many advanced features that may make wiring the unit appear complicated.

Wiring is actually very simple -- a minimum of three high voltage and 14 low voltages connections

are all that is required to take advantage of a majority of the DLC-XP/RC’s features. It is highly

recommended that you take a step-by-step approach to wiring and confirming proper DLC-XP/RC

operation:

1. Make the (10) low voltage control connections. These allow the DLC-RC to communicate with the

DLC-XP.

2. Make the high voltage connections. These will allow you to operate the DLC-XP/RC and attached

PULSAR pump. Power-up and test the DLC-XP/RC to confirm the connections and check for proper

operation.

3. Decide which low voltage Inputs (e.g., 4-20mA in) will be used and make those connections. Again,

power-up and test these connections.

4. Decide which low voltage Outputs (e.g., 4-20mA out) will be used and make those connections.

Again, perform the power-up and test cycle.

Refer to Section 6 – Start Up Instructions for details on how to perform the power-up tests.
