A VOID LOCATIONS WHERE THE DLC-XP/RC WOULD BE SUBJECTED TO EXTREME COLD OR
HEAT [ LESS THAN -18° C ELSIUS (0° F AHRENHEIT ) OR GREATER THAN 40° C ELSIUS (104°
F AHRENHEIT )] OR DIRECT SUNLIGHT . F AILURE 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.
