BE1-CDS220 Testing And Maintenance 13-19
•
Transmit the SN-IN1 command for each of the remaining seven contact sensing inputs that are
used in your system. Add the number of an input to the SN-IN command to check that input’s
name and labels.
•
Verify the recognition and debounce settings for each contact sensing input by using the SG-IN
command. When the SG-IN command is transmitted, the relay responds with the recognition and
debounce settings for each input. Reported settings use the format SG-IN1=recognition,
debounce.
Step 2. Verify contact sensing input connections.
•
Operate (or cause to operate) each contact associated with all contact sensing inputs that are
used in your system. You may operate them individually and verify that the BE1-CDS recognized
the contact operation or operate all of them and then verify the operation.
To verify that all inputs have been recognized, transmit the command RG-INPUT to retrieve
INPUT (12345678) information or, alternatively, transmit the command RG-STAT and review the
response at the tail end of the line INPUT (12345678). You may also view the input status on HMI
screen 1.4.1, \STAT\OPER\INPUT.
Output Contacts
Purpose: To verify output settings and connections.
Reference Commands: SN-VO, SL-VO, SG-HOLD
Step 1. Verify output settings.
•
Transmit the SN-VOA command to verify the virtual output A user-defined name, TRUE label, and
FALSE label.
•
Transmit the SN-VOA command for virtual outputs 1 through 15. Add the number of an output to
the SN-VO command to check that output’s name and labels.
•
Transmit the SL-VO command to obtain a list of all virtual outputs and their Boolean logic
equations. Verify that the desired virtual output equations match the reported equations.
•
Verify the programmable hold timer setting for each hardware output by transmitting the command
SG-HOLD. The output hold timer setting for each output is reported as enabled (1) or disabled (0).
Step 2. Verify output connections.
•
Output logic override control cannot be accessed from the HMI. Transmit the commands
ACCESS=, CS-OUT=ENA, CO-OUT=ENA, EXIT, and YES to enable the output logic control
override capability of the relay in order to operate each output contact.
•
Transmit the commands listed in Table 13-12. When the operate command is transmitted, the
corresponding output changes state for 200 milliseconds and returns to the normal state. Monitor
the specific output contacts in whatever manner you require to verify that the output connections
are valid. Remember, you have to gain access before you begin issuing commands and again if
the access time-out expires.
NOTE
In verifying output connections, we pulse the hardware outputs for 200 milliseconds. If you
have a specific output that requires a longer operate time to verify operation, substitute a
1 or 0 (depending on the output logic) for the P in the commands listed in Table 13-12.
After the output connection is verified, it is important to return the output to logic control
using the commands CS-OUTn=L; CO-OUTn=L <enter>.
•
If desired, you may disable the control override capability by transmitting the commands
ACCESS=, CS-OUT=DIS, CO-OUT=DIS, EXIT, and YES to the relay.
