Multi I/O Test Point Descriptions
Test Point # Functional Description Output
TP1 24
vdc
isolated drive voltage for analog output #1. Referenced to TP
2
Output #1
TP2 GND reference for TP
1
and all points within #1 output circuit
TP3
TP
3
& TP
4
are on opposite sides of a 100
Ω
resistor that is in series with the output
#1 current loop. Measure the DC voltage across these test points and divide by
100 to calculate the actual output current of channel #1.

vdc
isolated drive voltage for analog output #2. Referenced to TP
6
Output #2
TP6 GND reference for TP
5
and all points within #2 output circuit
TP7
TP
7
& TP
8
are on opposite sides of a 100
Ω
resistor that is in series with the output
#2 current loop. Measure the DC voltage across these test points and divide by
100 to calculate the actual output current of channel #2.
TP8
TP9 24
vdc
isolated drive voltage for analog output #3. Referenced to TP
10
Output #3
TP10 GND reference for TP
9
and all points within #3 output circuit
TP11
TP
11
& TP
12
are on opposite sides of a 100
Ω
resistor that is in series with the
output #3 current loop. Measure the DC voltage across these test points and
divide by 100 to calculate the actual output current of channel #3. TP12
TP13 24
vdc
isolated drive voltage for analog output #4. Referenced to TP
14
Output #4
TP14 GND reference for TP
13
and all points within #4 output circuit
TP15
TP
15
& TP
16
are on opposite sides of a 100
Ω
resistor that is in series with the
output #4 current loop. Measure the DC voltage across these test points and
divide by 100 to calculate the actual output current of channel #4. TP16
6.4 OPERATIONAL DESCRIPTION—Menu Structure and User Interface
The Enhanced Remote Panel is menu driven. Operational and configuration
parameters are viewed and changed through the display menu screens. The
system configuration parameters are password protected. Protected screens can
be accessed with the supervisor password or the Security Key Switch.
Operational and test parameters may be viewed and/or changed by scrolling
through the menus using the “
↑
”, “
↓
”, “Page Up”, “Page Down”, “ESC”, and “
↵
”
keys. The functions of these keys are described on each menu screen. The ESC
key will return you to the previous menu. Password protected screens will prompt
for the password before displaying the screen. To use the Security Key Switch it
must be in the ON position
before that screen is selected.
6.4.1 Memory Test
The Memory Test runs at power up before the logo screen is displayed. It tests all
the used areas of the RAM ICs. If they pass, a message is briefly displayed on the
screen before the logo. If either one fails, a message indicating which chip failed
remains on the screen and the CPU halts.
