Main Pcb Jumpers - Cardinal 220 Quick Setup Manual

Main PCB Jumpers

(See Figure No. 7)
J6 - AUTO-ON JUMPER
The AUTO-ON jumper J6, when connected, 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. See Figure No. 7 for jumper
location.
J7 - TEST JUMPER
The TEST jumper J7, when connected, will turn the backlight on, disregarding the LIGHT ON=
setting (refer to Setup Review for explanation of LIGHT ON). See Figure No. 7 for jumper location.
J8 - 8V EX JUMPER
The 8V EX jumper J8, when connected, allows the 220 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 (J8 closed ). Operating
with the load cell excitation voltage set to 12 VDC will result in an unstable weight display. See
Figure No. 7 for jumper location.
J10 - ACTIVE REMOTE OUT JUMPER
The Active Remote Out jumper J10, when connected, allows the 220 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 P8 pins 2 through 9 and the
negative wire from the relays to P8 pin 10 (GND/SHLD). See Figure No. 7 for jumper and
connector P7 location.
For completely isolated outputs, J10 must be open (positioned on one plug-in pin only or removed)
and the user must provide 5 to 12 VDC to P8 pin 1 (+SRC) and a ground return to the load. The
load must still be 200 ohms or greater. Note that P8 pin 10 (GND/SHLD) is not connected.
J11 - ACTIVE REMOTE IN JUMPER
The Active Remote In jumper J11, when connected, allows the 220 indicator to supply (source)
5 VDC to a remote input circuit. Connecting P9 pins 1 through 9 to P9 pin 10 (GND) through a
switch will cause the selected action. See Figure No. 7 for jumper and connector P9 location.
For completely isolated inputs, J11 must be open (positioned on one plug-in pin only or removed)
and the user must provide 5 to 12 VDC to P9 pin 1 (+SRC) and a ground return to the switch
connected to P9 pin 2 through 9. Note that P9 pin 10 (GND) is not connected.
J12 AND J13 - SENSE JUMPERS
If the sense leads are NOT used, you must install plug-in jumpers at J12 and J13 adjacent to the
terminal block. These jumpers attach the sense leads to the excitation leads. If sense leads ARE
used (as in motor truck scales), these plug-in jumpers should be positioned on one plug-in pin only
or removed and stored for later use. Refer to Figure No. 7 for the location of the jumpers.
J14 - GND TO CHASSIS JUMPER
This jumper when installed connects the analog circuit ground to the indicator chassis ground.
Refer to Figure No. 7 for the location of the jumper.
J15 - DEAD LOAD BOOST JUMPER
For very low dead loads (less than 10% of the combined load cell capacity) connect the dead load
boost jumper J15 on the printed circuit board. Refer to Figure No. 7 for the location of the jumper.
