INSTALLATION
Logic Level Output
Your Model 225 indicator has logic level outputs that can be used to control peripheral devices
used to signal when the weight is within preset limits. Note that these outputs (defined on the
next page) are at logic level and cannot drive external devices directly. Solid-state relays can
be used to accept the logic level output from the 225 and in turn, drive the external device.
Output Cable Installation
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 a gland connector for the cable.
3. Slip the cable through the gland connector and into the enclosure.
4. Remove 2 inches of the cable 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 (P15).
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.
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. 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. 1.
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.
OUTPUT (closed) 28-240VAC @ 3A maximum for each plug-in relay
CONTROL INPUT 5VDC @ 12mA from the 225 main pc board assembly P8
CONNECTION Removable plug-in screw terminals for up to 14 AWG wire
NOTE! All relays are the normally-open type that will open when power to indicator is lost.

OPTICALLY ISOLATED REMOTE INPUTS
The Model 225 has seven (7) programmable inputs that may be used to remotely (up to 100
feet) initiate various functions within the indicator. These inputs are accessed via a terminal
block (P17) on the back of the Main PC board. The 7 inputs are defined on the following page.
Remember that the input must be connected to GND to initiate the function.
Input Cable Installation
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 a gland connector for the cable and slip the cable through the gland connector
and into the enclosure.
3. Remove 2 inches of the cable outer insulation jacket and then remove 1/4 inch of
insulation from each of the wires.
4. Connect each of the wires to the Remote Input terminal block (P17).
5. To terminate a wire, use a small flat blade screwdriver and press down on the release

6. Repeat procedure until all wires are in place.
AC Input Relay Board(s)
The AC Input Relay Board(s) are mounted in an external junction box for use with the 225
Indicator. The RB4-ACIN (115 VAC) or RB4-ACINV (230 VAC) contain one board and
supports 4 inputs (jumper selectable). The RB8-ACIN (115 VAC) or RB8-ACINV (230 VAC)
contain two boards and supports seven inputs that are jumper selectable. The relay board
used in the 115 VAC versions is Cardinal p/n 8200-C324-0A. The 230 VAC version uses relay
board Cardinal p/n 8200-C324-1A. Connect the devices as shown in Figure No. 2.
INPUT RELAY TYPE IAC-5 90 to 140 VAC @ 6mA maximum for each plug-in relay
INPUT RELAY TYPE IAC-5A 180 to 280 VAC @ 6mA maximum for each plug-in relay
OUTPUT 5VDC @ 12mA from the 225 main pc board assembly P9
12VDC @ 12mA maximum from external source
CONNECTION Removable plug-in screw terminals for up to 14 AWG wire
NOTE! AC INPUT RELAYS ARE VOLTAGE DEPENDENT.
A DIFFERENT RELAY IS REQUIRED FOR 115 VAC AND 230 VAC!

MAIN PC BOARD JUMPERS
J4 (PWC1-8) and J5 (PWC9-16) – ACTIVE REMOTE OUT JUMPERS
When installed, these jumpers allow the 225 indicator to supply (source) 5 VDC to a solid-state
relay or other load of 200 ohms or greater. To operate from the 5 VDC source, the positive
connection from the relays must be connected to P15 (P16) pins 2 through 9 and the negative
wire from the relays to P15 (P16) pin 10 (GND). See Figure No. 9 for connector P15 location
and Figure No. 10 for connector P16 location.
For completely isolated outputs, J4 (J5) must be open (on one pin only or removed) and the
user must provide 5 to 12 VDC to P15 (P16) pin 1 (+SRC) and a ground return to the load.
The load must still be 200 ohms or greater and P15 (P16) pin 10 (GND) is not connected.
J6 (REMOTE IN) – REMOTE IN JUMPER
When installed, this jumper allows the 225 indicator to supply (source) 5 VDC to a remote input
circuit. Connecting P17 pins 1 through 9 to P17 pin 10 (GND) through a switch will cause the
selected action. See Figure No. 8 for connector P17 location.
For completely isolated inputs, J6 must be open (on one pin only or removed) and the user
must provide 5 to 12 VDC to P17 pin 1 (+SRC) and a ground return to the switch connected
to P17 pin 2 through 9. Note that P17 pin 10 (GND) is not connected.
J1 (AUTO ON) – AUTO-ON JUMPER
When installed, this jumper will cause the indicator to power on automatically whenever power
is applied to the power input connector. If power is lost momentarily and then reapplied, the
indicator will turn on without pressing the ON key.
J2 (TEST) – TEST JUMPER
When installed, this jumper will turn the backlight on, ignoring the BACK LITE= setting.
J3 (8V) – 8V EXCITATION JUMPER
When installed, this jumper allows the 225 indicator to supply 8 VDC excitation voltage when a
remote (external) 12 VDC battery is used to power the indicator. To operate from the 12 VDC
battery, the load cell excitation voltage MUST be set to 8 VDC (J3 closed). Operating with the
load cell excitation voltage set to 12 VDC will result in an unstable weight display.
J7 (+SEN) and J9 (-SEN) – SENSE JUMPERS
If the sense leads are NOT used, you must install jumpers at J7 and J9 (near the P13 and P14
terminal blocks). These jumpers connect the sense leads to the excitation leads. If sense
leads ARE used (as in motor truck scales), these jumpers should be open (on one pin only or
removed).
J8 (DLB) – DEAD LOAD BOOST JUMPER
For very low dead loads (less than 10% of the combined load cell capacity), connect J8, the
DLB (dead load boost) jumper on the printed circuit board.
J10 (GTC) – GND TO CHASSIS JUMPER
When installed, this jumper connects the analog circuit ground to the indicator chassis ground.

8200-M564-O1 y225 Check Weigher Page 7
RE-INSTALLING THE REAR PANEL
After all terminations have been made;
1. Remove the excess cable from the instrument enclosure and securely tighten each of
the cable gland connectors.
yDo not over-tighten these connectors but make certain they are snug.
yDO NOT USE TOOLS! Finger-tighten only!
2. Ensure any unused gland connectors are plugged and replace the rear panel.
3. Secure the rear panel with the 14 acorn nuts removed earlier.
4. Follow a diagonal pattern when tightening the acorn nuts.

¾The relay state is based on using Cardinal Scale relays (p/n 6850-1013). If using relays
other than those supplied by Cardinal Scale, refer to the relay manufacturers specifications.
NOTE! When power to the indicator is lost, the output returns to a Low State condition.
2.AUTO PRINT=XXX – AUTOMATIC PRINT
The automatic print feature will cause an optional printer to print when the weight is in the
ACCEPT range and STABLE. STABLE is defined by the STABLE= and STBL CNT=
parameters settings in the SCALE 1 SETUP MENU #1.
The display will show AUTO PRINT=XXX where XXX is the current value. If the setting
displayed is acceptable, continue to the next section.
To change the current setting, press the 2 key and then the ENTER key.
