Checking the DC Power Supply Board, 10-14 | Teledyne 300M specs

Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A

The DAC's are operated in bipolar mode allowing a "live zero" on all output. In addition, DAC's 0 and 1 (Strip Chart and DAS) physically provide a Full Scale of 120% of the nominal selected value with the microprocessor providing pre-scaling to achieve the nominal value. This combination provides 20% over-range capability. The microprocessor is also used to adjust for offset and gain needed to match DAC outputs to external voltage standards, and no on board adjustments are needed or provided for this function.

The outputs of all DAC's are "looped-back" to Analog input (via the Mother Board) channels. This loop back allows for automatic microprocessor checking of A/D.

10.6.3.3 Digital I/O Lines

32 Digital Lines are used to provide the primary means for the microprocessor to control various analyzer functions(valves, heaters, etc.) and to send and receive status conditions to/from external equipment. These lines are configured as 8 digital inputs and 24 digital outputs. The convention for all Digital I/O Lines is High (+5V)-True, Low (0V)-False.

10.6.4 Checking the DC Power Supply Board

A schematic and physical diagram of the DC Power Supply Board are shown on Drawings 015 and 016 in Appendix C.

The overall performance of the DC Power Supply Board can be checked by observing the value of the DCPS test functions. If this value, a composite of five regulator value recorded in Table 1-1of this manual under Test Values, the outputs of the individual regulators should be checked by measuring for the following voltages:

1.Remove Plugs J8, J6, and J13 from the front of the Power Supply Module. Verify that the following voltages are present:

A.+11.6VDC between J8 pins 2 and 4

B.+24VDC between J6 pins 12 and 13

C.9.5VAC between J13 pins 4 and 5

D.15VAC between J13 pins 3 and 2

E.38VAC between J13 pins 6 and 7

If any of these voltages is not present, the Power Supply Module is defective and should be replaced.
