Table 9-3: Summary of Diagnostic Modes

DIAG Mode

Description

SIGNAL I/O

Gives access to the digital and analog inputs and outputs on

 

the V/F board. The status or value of all of the signals can be

 

seen. Some of the signals can be controlled from the keyboard.

 

Table 9-4 gives details on each signal and information on

 

control capabilities.

 

NOTE:

 

Some signals can be toggled into states that indicate warnings

 

or other faults. These settings will remain in effect until DIAG

 

mode is exited, then the M200AU will resume control over the

 

signals.

 

 

ANALOG OUTPUT

Causes a test signal to be written to the analog output DAC's.

 

The signal consists of a scrolling 0%, 20%, 40%, 60%, 80%,

 

100% of the analog output value. The scrolling may be

 

stopped by pressing the key underneath the % display to hold

 

the current value. The exact voltage values depend on the

 

switch settings on the V/F board amplifiers.

 

 

D/A CALIBRATION

The analog output is created by 4 digital-to-analog converters.

 

This selection starts a procedure to calibrate these outputs.

 

Refer to Section 9.3.3.1 for a detailed procedure.

 

 

TEST CHANNEL

Allows several different internal voltages to be routed to an

 

analog output port. Useful for diagnosing intermittent faults.

 

 

OPTICAL TEST

Sets the M200AU into a known state and turns on an LED

 

near the PMT to test the instrument signal path. See Section

 

9.1.3.3 for details on using this test.

 

 

ELECTRICAL TEST

Tests just the electronic portion of the PMT signal path. Used

 

in conjunction with optic test, see Section 9.1.3.2.

O3 GEN OVERRIDE

This function switches the power to the ozone generator. It

 

does not indicate the OFF/ON status of the generator

 

 

RS-232

Causes a 1 second burst of data to be transmitted from the RS-

 

232 port. Used to diagnose RS-232 port problems. See Section

 

9.1.3.7, 9.3.2 for RS-232 port diagnostic techniques.
