IC6 Operating Manual
15.7.1 Troubleshooting the IC6
Table 15-7 Troubleshooting the IC6
SYMPTOM CAUSE REMEDY
1. Power on LED not
illuminated
a. Blown fuse/circuit breaker
tripped
a.Have qualified personnel
replace fuse/reset circuit
breaker
b. Electrical cord unplugged
from wall or back of IC6
b. Reconnect power cord
c. Incorrect line voltage c. Have qualified personnel
verify line voltage, verify the
IC6 is configured for the
correct voltage
2. IC6 "locks" up a. Cover or back panels not
attached to the IC6
a. Ensure all covers and
panels are in place and
securely fastened
b. High electrical noise
environment
b. Reroute cables to reduce
noise pickup (1 ft away from
high power conducting lines
makes a sizable reduction in
the amount of noise entering
the IC6), keep all ground
wires short with large surface
area to minimize ground
impedance
c. Poor grounds or poor
grounding practice
c. Verify proper earth ground,
use appropriate ground
strap, eliminate ground loops
by establishing the correct
system grounding, verify
proper IC6 grounding
3. IC6 does not retain
parameters on power down
(loss of parameters on power
up)
a. Faulty static RAM a. SRAM battery has a
normal life expectancy of ten
years, contact INFICON
service department
b. Power supply problem b. Contact INFICON service
department
4. Some keys on front panel
function while others do not
a. Faulty keypad or faulty
keypad ribbon cable
a. Contact INFICON service
department
5. All keys on the front panel
fail to function
a. IC6 is "locked" up a. Turn power to OFF or to
STBY, then to ON, see item 2
above
