RELAY PCA
The Relay PCA can be most easily checked by observing the condition of its status LEDs
(see Section 5.7.5.2), and using the Utilities>Diagnostics>Digital Outputs menu (see
Section 5.7.3) to toggle each LED ON or OFF.
If D1 on the Relay PCA is flashing and the status indicator for the output in question
(Heater power, Valve Drive, etc.) toggles properly using the Signal I/O function, then the
associated control device on the Relay PCA is bad.
DATA ACQUISITION (DAQ) PCA
If the warning message, BENCH COM WARNING, appears on the front panel display,
check that the serial cable between the DAQ PCA and the CPU is seated properly.
If any adjustment to that cable does not resolve the issue, the DAQ PCA can be checked
by observing LEDs D10 through D13 (Figure 5-11). If they are not blinking, the DAQ may
need to be changed. Although not all test points (TP) on the DAQ are used, if the values
for TP14 through TP21, TP23 and TP24 do not come back as expected (Figure 5-11),
contact Teledyne API Technical Support for a replacement.
