PRIMEX®2 CW6CDC Level Controller User Manual
The CW6CDC level controller is a simple, easy-to-use microprocessor-
based controller capable of monitoring any 4-20 mA signal. It has six
programmable relay outputs that can be used for control and alarm.
The transducer input zero and span are fully configurable. A simulation
mode allows the user to test set-points and relay operation.
CW6CDC LEVEL CONTROLLER INTRODUCTION
The standard CW6CDC level controller kit contains (see Figure 2 on
page 5 of this manual):
• one CW6CDC level controller
• two mounting brackets for panel mounting
• a three pin power supply connector block (P1)
• a 18 pin relay output connector block (P2)
• a five pin transducer connector block (P3)

INSTALLATION & DIMENSIONAL DATA

PRIMEX®6 CW6CDC Level Controller User Manual
1. POWER (Terminal P1)
Connect power to terminal 1 and 2: the unit requires 24 VDC (+/- 10%).
2. TRANSDUCER (Terminal P3)
For loop powered transducers (2 wire) connect power conductor to terminal
1 and 2. If the cable is protected with an overall shield, connect the shield
to terminal (3). Terminal 4 and 5 must be connected if an output follower is
not required. If no valid input is present, the controller will display SENSOR
and all outputs will be de-energized.
NOTE: To avoid ground loops, the shield of the signal cable must only be
grounded at one end.
3. OUTPUT RELAY CONNECTIONS
The relay outputs are rated up to 10 A (resistive) at 240 VAC, fuse
protection is required individually or as a group.

ELECTRICAL CONNECTIONS

PRIMEX®7 CW6CDC Level Controller User Manual
LEFT AND RIGHT ARROW KEYS
are used to navigate through the menu items. These
arrow keys can also be used to back out when in editing
and simulation mode.
ENTER KEY
is used for selecting a menu item for editing. This key is
also used after a value has been edited to store in memory.
UP AND DOWN ARROW KEYS
is used to increase or decrease the current value being
edited.
NOTE: The display automatically returns to “level” after 20 seconds of
inactivity, regardless of where it was left.
Pressing once will increment the current value by one unit. Pressing and
holding will begin repeatedly incrementing after a short delay. If the
operator continues to hold the key, the value continues to increment at a
faster rate.

LEVEL DISPLAY
The adjustable ON and OFF function allows for an individual hysteresis or
differential setting of each set-point. For an emptying application, the ON set-
point must be greater than the OFF set-point. For a filling application, the ON
set-point must be less than the OFF set-point (Refer to FIGUIRE 5).
NOTE: For proper operation of the CW6CDC controller, the ON and OFF
set-points must not be set to the same value.
