Preset Weight Comparator/Checkweigher Logic Level Output; Ac Output Relay Board(S) - Cardinal 225 Installation And Technical Manual

Preset Weight Comparator/Checkweigher Logic Level Output

If you so choose, you may use the logic level outputs from your Model 225 indicator's preset
weight comparators or checkweigher to control peripheral devices used to manage the flow of
material or signal when the weight is within preset limits. Note that these outputs are at logic
level and cannot drive external devices directly, with the exception of the Cardinal 2XX-OU
CHECK WEIGHER LIGHT BAR. Solid-state relays can be used to accept the logic level
output from the 225 and in turn, drive other external devices.
1. If the rear panel of the indicator has been removed, proceed to step 2. Otherwise, remove
the 14 acorn nuts securing the rear panel to main housing
2. Loosen the gland connector for the cable. Refer to Figure No. 2 for the gland connector
layout.
3. Slip the cable through the gland connector and into the enclosure.
4. Referring to Figure No. 4, remove 2 inches (not 5 to 6 inches) of the outer insulation jacket
5. Next, remove 1/4 inch of insulation from each of the wires.
6. Connect each of the wires to the Remote Outputs terminal block (P19 or P18) referring to
Figure No. 13 for terminal block locations.
7. To terminate a wire, use a small flat blade screwdriver and press down on the release bar
for the terminal. Insert the wire into the terminal opening. Remove the screwdriver,
allowing the release bar to return to its original position, locking the wire in place. See
Figure No. 5.
8. Repeat procedure until all wires are in place.

AC Output Relay Board(s)

The AC Output Relay Boards are mounted in an external junction box for use with the 225
Indicator and can be purchased from Cardinal. The RB4-ACOUT contains one board and
supports four outputs (jumper selectable). The RB8-ACOUT contains two boards and
supports eight outputs. The relay board used in both is (Cardinal p/n 8539-C062-0A).
Connect the devices to be controlled as shown in Figure No. 9 and 10.
The individual relays can be configured to be on (closed) or off (open) at weights under the
preset weight then switch at the preset weight from on-to-off or off-to-on by setting the under
weight condition to on or off during setup and calibration or setup review.
