ERROR CODE PROBABLE CAUSE SOLUTION
#14 Rack Jam nn A rack jam was detected. The
number
搉
n?describes the area in
which the jam occurred:
nn=1: The rack jam happened in
the In Feed area: sensor
PH2 was OFF and sensor
PH1 was ON at the
beginning of an in feed
operation but PH1 did not
turn OFF afterwards.
nn=2: The rack jam happened in
the In Feed area: sensor
PH2 was OFF and sensor
PH1 was ON at the
beginning of an in feed
operation. PH1 then turned
OFF but PH2 was unable to
turn ON after a full-stroke of
the In Feed unit.
nn=3 The rack jam happened in
the Cross Feed area:
sensor PH2 was unable to
turn OFF again after turning
ON at the beginning of a
rack cross feed operation.
Attempt to clear the rack jam. Verify
instrument is level. Clean the base
(Transfer Plate) with a damp, clean
cloth if the base is wet or dirty. Dry
base, then run unit again. If error
persists, do the following:
1. If jam always happens with the
same rack, replace rack.
2. Inspect the Rack Guides for
proper rack clearance (paragraph
8-3, page 8.3).
3. Run Sensor Monitor test in
Service Mode (see paragraph
7-2-7 on page 7.8). Check sensor
using a rack to activate the
sensor.
4. If sensor(s) fail Sensor Monitor
test, look for any obstructions on
the
搘
indow?of the affected
sensors.
5. Remove instrument covers and
reseat sensor connector. Then
use a VOM meter to check the
sensor output, see Figure 5,
Schematic page 12.11. Do not
use chassis ground; use an N24V
terminal on terminal strip TB1 in
front of the power supply. Look
for 0 VDC on connector pin 2
(white wire) with a rack at the
sensor and 24 VDC with nothing
at sensor.
6. If sensor works intermittently,
consider adjusting it (see
paragraph 8-5, page 8.5).
7. Repair, reseat or replace:
a. The sensor(s)
b. The Mother Board
c. The CPU and/or I/O PC
Boards.
