Basic Relay Operations
Operating the Relay Inputs and Outputs
Step 3. Perform the pulse operation.
a. Type PULSE OUT204 <Enter>.
The relay confirms your request to pulse an output with
a prompt such as that shown in Figure 10.13.
b. Type Y <Enter> at the prompt.
You will see or hear the indicating device turn on for a
second and then turn off.
>PULSE OUT204 <Enter>
Pulse contact OUT204 for 1 seconds(Y/N) ? Y <Enter>
>
Figure 10.13 Terminal Display for PULSE Command
You can also pulse an output for longer than the default 1-second period. If
you enter a number after the PULSE command, that number specifies the
duration in seconds for the pulse. For example, if you enter PULSE
OUT204 3 <Enter>, the relay pulses OUT204 for 3 seconds.
Pulsing a Control Output: Front Panel
The procedure in the following steps shows you how to use the front-panel
display and navigation pushbuttons to check for proper operation of the relay
control outputs. See Section 7: Front-Panel Operations for information on
using the relay front panel.
Step 1. Attach an indicating device (an ohmmeter with a beep sounder
or a test set) to the terminals for control output OUT201.
This output is a standard control output and is not polarity
sensitive. For more information on connecting control outputs,
see Control Outputs on page P.2.6.
Step 2. View the front-panel display.
After applying power to the relay, note that the LCD shows a
sequence of screens called the
ROTATING DISPLAY.
(Also, if you do not operate the front panel for a certain period,
the relay will enter front-panel time-out mode and you will see
the sequential screens of the
ROTATING DISPLAY.)
Step 3. Press the ENT pushbutton to view the
MAIN MENU, similar to that
at the top of Figure 10.14.
