4.
Before proceeding, clean the load cell connector and cable connector with isopropyl alcohol
and cotton swabs, then dry with a hair dryer.
Do not overheat
. Reconnect and operate the
system for one day to see if the problem is fixed. If the problem is not fixed, continue to step.
5.
If two load cells are connected per VSL Vulcoder, follow steps 5a and 5b.
a.
Disconnect the cable to the right load cell. Watch the meter display the number for a
period of 5 minutes. If it wanders more than 200 lb (100 kg), make a note of it. Then
clean and reconnect the right load cell.
b.
Disconnect the cable to the left load cell. Watch the meter display the number for
period of 5 minutes. If it wanders more than 200 lb (100 kg), make a note of it. Then
clean and reconnect the left load cell.
If any one of the load cells wanders more than 200 lb (100 kg), perform the Leakage and Resistance
tests,
(Section 6.2.1 and 6.2.3). If both of the load cells wanders more than 200 lb (100 kg), then the
VSL Vulcoder may be faulty and needs to be checked, (Section 6.3.4 “VSL Vulcoder Check-Out
Procedure”).
If four load cells are connected per VSL Vulcoder, follow steps 5c through 5f.
c.
For VSL Vulcoders with 4 load cells, disconnect the cables to all the load cells except
the right front load cell. Watch the meter display a number for a period of 5 minutes.
If it wanders more than 200 lb (100 kg), make a note of it.
d.
Disconnect right front load cell and reconnect right rear load cell. Watch the meter
display for 5 minutes. If it wanders more than 200 lb (100 kg), make a note of it.
e.
Disconnect the right rear load cell and reconnect the left rear load cell. Watch the
meter display for 5 minutes. If it wanders more than 200 lb (100 kg), make a note of it.
f.
Disconnect the left rear load cell and reconnect the left front load cell. Watch the meter
display for 5 minutes. If it wanders more than 200 lb (100 kg), make a note of it. If
any one of the load cells wanders more than 200 lb (100 kg), perform the Leakage and
Resistance tests, (Sections 6.2.1 and 6.2.3). If all the load cells wander more than 200
lb (100 kg) then the VSL Vulcoder may be faulty and needs to be checked (Section
6.2.4 “VSL Vulcoder Check-Out Procedure”).
