The SHO Command (Showset) on page 5.16 explains the other settings
available with variations of the SHO command.
Outputs
Step 1. Purpose:
Verify that contact outputs operate when you execute the
PULSE command.
Method:
a. Isolate all circuitry connected to the output contacts.
b. Set the target LEDs to display the contact outputs by
typing TAR 12 <Enter>. The front-panel LEDs should
now follow Row 12 of the Relay Word where the
outputs are listed.
c. Execute the PULSE n command for each output
contact.
d. Verify that the corresponding target LED illuminates
and that the output contact closes for approximately one
second. For example, type PUL OUT1 <Enter> to test
output contact
OUT1.
The response of a programmable alarm output contact
to a PULSE command is discussed in the Output
Contacts on page 3.39.
Inputs
Step 1. Purpose:
Verify that logic inputs assert when control voltage is applied
across the respective terminal pair.
Method:
a. Set the target LEDs to display the contact inputs by
typing TAR 4 <Enter>. The fourth and fifth front-
panel LED should now follow logic inputs IN1 and
IN2, which are in Relay Word Row 4.2.
