DIAGNOSTIC TESTS AND 2ND FUNCTION KEY

To access the Diagnostics and 2nd Functions, the unit must be in the “Ready” mode,

press

2ND FUNC,

then enter the number of the diagnostic test desired. To exit the

diagnostic test, press

2ND FUNC a

gain.

Diag. 0 - Custom User Label Programming -

THIS IS NOT A TEST!

Refer to Section VIII,

“Programming the Display, ”

for information.

Diag. 1 - Keypad Test -

In this test, pressing each key on the front panel keypad will

result in the alphanumeric display showing the name of the key pressed. The numeric
display will show 0000 for keys that are not numbers, and will display the numeral (for
example: 1111, 2222, etc.) when the number keys are pressed. If any key does not
produce the proper display, that key may not be functioning. Contact the factory if this
occurs.

Diag. 2 - Display Test -

This test is to make sure that all of the LED segments on the

displays and all of the LED indicator lights are working correctly. During the test, the
Numeric display will scroll through all the numbers (i.e.

1111,

2222, 3333, etc.) an d

will place the decimal point in each possible location. The alphanumeric display will
also display all of the numbers (i.e.

11111111,

22222222, etc.). The six LEDs on the

front of the unit indicating switch position and operating condition will light up one at a
time. If a segment is missing, or an LED indicator light fails, contact the factory.

Diag. 3 - Input Switch Test -This

is a test for each of the remotely wired inputs.

Each possible input

(Local/Remote, Keypad Lockout, Forward/Reverse, etc.)

is represented by a 0 or a 1 on the alphanumeric display. The

E-Stop, Run, Jog,

and

Stop inputs are represented by a 0 or a 1 on the speed display. Toggle the input to
check whether or not it is properly wired. When the digit corresponding to that input is
displayed as 0 the switch is Open, when it is displayed as 1 it is activated. E-Stop and

Stop

are 1 when opened and 0 when closed.

Left to right,

the eight digits on the alpha-

numeric display (00000000) correspond to the following inputs: Closed/Open Loop;
Master/Follower; Forward/Reverse; Keypad Unlocked/Locked out; Set Point 1(3)/2(4);
Set Point 3 & 4 Disabled/Set Point 3 & 4 Enabled; No Scroll/Scroll Down; No Scroll/
Scroll Up. Left to right, the four digits on the numeric display (0000) correspond to the

following command inputs: E-Stop; Run; Jog; Stop.

Diag. 4 - Memory Test -

This is an internal test by the micro-processor on its

memory locations. The alphanumeric display will show “Test ROM” for a few seconds,
then it will show either, “ROM ok” or “Fail.” If the test fails, contact the factory.

Diag. 5 - Alarm Output Test -

This is a test of the Status and Alarm outputs. In this

test, pressing a 1 through 6 on the keypad will result in completion of one of the Output
circuits. When in this diagnostic, the alphanumeric display will read “Output” until a
key (1 through 6) is pressed, then it will name the output being tested and the circuit
will be completed. A light wired into the circuit will illuminate, a relay will actuate, or
an alarm will sound, depending on how the circuit is wired. After an output is tested,

press the STOP button to turn the output off. To exit the Diagnostic, press the Stop, then

the 2ND FUNC key. The following numbers correspond to the following outputs:

1 = Ramp Complete; 2 = Zero Speed; 3 = High Alarm; 4 = Low Alarm; 5 = Deviation

Alarm; 6 = Drive Enable

Diag. 6 - Communications Test -

This test is used to test the RS422 hardware. To

perform the test, place a jumper wire between the Send and Receive lines at the terminal
(RXD- to TXD- and RXD+ to TXD+). The MicroSpeed 196 tests its communication
circuitry to make sure it is functioning. If it is, the alphanumeric display will read “Pass”
and the numeric display will name the node address. If it is not functioning properly, the
alphanumeric display will display “Fail.”

Diag. 7 - Reset to Factory Programming -

This

is Not a Test. Pressing

2nd

FUNC,

then accessing Diag. 7 will reset the programming in memory to the factory

defaults (see Appendix I for factory default settings). The alphanumeric display will read
“Reset”.

Diag. 8 -

Not Used.

Diag. 9 - Digital Speed Pot -

This function is explained in Section IX
