10.6. SUBSYSTEM CHECKOUT
The preceding sections of this manual discussed a variety of methods for identifying
possible sources of failures or performance problems within the analyzer. In most cases
this included a list of possible causes and, in some cases, quick solutions or at least a
pointer to the appropriate sections describing them. This section describes how to
determine if a certain component or subsystem is actually the cause of the problem being
investigated.
10.6.1. AC POWER CONFIGURATION
The T100 digital electronic systems will operate with any of the specified power regimes.
As long as instrument is connected to 100-120 VAC or 220-240 VAC at either 50 or 60
Hz it will turn on and after about 30 seconds show a front panel display. Internally, the
status LEDs located on the Motherboard, the Relay PCA and the CPU should turn on as
soon as the power is supplied.
On the other hand, the analyzer’s various non-digital components, such as the pump and
the AC powered heaters, require that the relay board be properly configured for the type
of power being supplied to the instrument.
ATTENTION
COULD DAMAGE INSTRUMENT
Plugging the analyzer into a power supply that is too high a voltage or frequency
can damage the pump and the AC Heaters.
Plugging the analyzer into a power supply that is too low a voltage or frequency
will cause these components to not operate properly.
If the pump and the heaters are not working correctly and incorrect power configuration is
suspected, check the serial number label located on the instrument’s rear panel (refer to
Figure 3-4) to ensure that the instrument was configured for the same voltage and
frequency being supplied.
If the information included on the label matches the line voltage, but you still suspect an
AC power configuration problem:
For the heaters, check the power configuration jumpers located on the relay board (refer
to Figure 10-4).

If the Jumper block is WHITE the heaters are configured for 115 VAC at 60 Hz.

If the Jumper block is BLUE the heaters are configured for 220, 240 VAC at 50 Hz.
