Issue 4 Installation and Operation Manual
Contact Sense Procedure
Perform the following procedure for each connection to an external relay at the site. The procedure
below configures an individual contact port using the contact port number
c
[#] in the command
string. If desired, you can configure a parameter for all contact ports at once by typing
all
in place
of
c
[#].
1. Set the normal operating state of each contact port by typing:
configure contact normal-state c
[#] [
NO
or
NC
]
where
c
[#] is contact port 1 - 8, and the normal state for that port is Normally Open (
NO
)
or Normally Closed (
NC
). Default is Normally Open.
2. If desired, enter an alphanumeric description of the contact port by typing:
configure contact description c
[#] [“contact description”]
Note
If a space is desirable in the description, you must use a double-quoted string, as shown above.
3. Enable the contact port by typing:
configure contact enable c
[#]
4. Repeat the procedure for each external relay to be monitored by Contact Sense.
5. Disable any contact ports that will not be monitored by Contact Sense by typing:
configure contact disable c
[#]
6. The SC-SDT is now monitoring the enabled contact ports.
• To view the current configuration parameters and status of all contact ports including
current state and alarm status of enabled contact ports, type:
show contact
• To manually clear an active alarm condition, type:
configure contact clear
c
[#]
If after clearing, the alarm condition still exists, a new alarm condition is generated
resulting in a new SNMP Trap.
