Main Pcb Jumpers; Re-Installing The Front Panel - Cardinal 212G Installation And Technical Manual

INSTALLATION, CONT.

Main PCB Jumpers

J1 - BATTERY CHARGE MODE (Not Applicable)
J2 - AUTO-ON JUMPER
The AUTO-ON jumper J2, 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.
J3 - 8V EXCITATION JUMPER (Not Applicable)
J4 AND J5 - SENSE JUMPERS
If the sense leads are NOT used, you must install plug-in jumpers at J4 and J5 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.
J10 - DEAD LOAD BOOST JUMPER
For very low dead loads (less than 10% of the combined load cell capacity) connect the dead
load boost jumper J10 on the printed circuit board.
J11 – PWC SRC (SOURCE)
The J11 jumper, when connected (closed) supplies 12 VDC from the 212G/212GX indicators
to a solid-state relay or other load of 200 ohms or greater. When J11 is open (positioned on
one plug-in pin only or removed), the 12 to 24 VDC must be provided from an external source
to P10-6. The load must still be 200 ohms or greater.

Re-Installing the Front panel

After all terminations have been made, remove the excess cable from the instrument enclosure
and securely tighten each of the cable gland connectors. Do not over-tighten these connectors
but make certain they are snug. DO NOT USE TOOLS! Finger tighten only! Insure any
unused gland connectors are plugged.
1. Make certain no cables or wires are exposed between the main housing and front panel
2. Place the front panel onto the main housing.
3. Secure with the 12 mounting screws removed earlier.
4. Follow a diagonal pattern when tightening the screws.
