Troubleshooting
6.1
Periodic Maintenance
There are two external fuses in each power supply module located in a slide out drawer just to the left of
the power switch. The fuses are rated at 3.15A, 250V.
CAUTION
For personal safety, always replace the fuses with the correct type and rating.
6.2
Alarm Masks
The RCS20 performs a high degree of self-monitoring and fault isolation.
A feature exists that allows the user to ‘Mask’ out certain alarms as explained below. Alarms that are
recorded in the event buffer are the same as the alarm buffer.
CAUTION
Masked alarms can cause undesirable performance.
When an alarm is masked, the Front Panel LEDs and the Fault Relays do not get asserted, but the Alarm
will still be displayed. This feature is very helpful during debugging or to lock out a failure of which the
user is already aware.
