Teledyne API M100E Analyzer Operation Manual Troubleshooting & Repair

12.6. 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.
12.6.1. AC POWER CONFIGURATION
The M100E 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, Relay PCA and 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.
CAUTION
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 3-2) to ensure that the instrument was
configure
d 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 12-4).
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.
