-toggle relay when input changes-
When a voltage is applied to the input or removed from the
input the relay will change states.
-pulse relay when input on-
When a voltage is applied to the input, the relay will pulse for the
Pulse Duration specified. The voltage may remain on or be removed and the pulse time
will not be affected. If the voltage is applied, removed, and then re-applied before the end
of the pulse time, the Pulse Duration timer will be re-started (it will re-start each time a
voltage is applied) and the relay will continue to remain
on
until the timer expires.
-pulse relay when input off-
When a voltage is removed from the input, the relay will pulse for the
Pulse Duration specified. The voltage may remain off or be re-applied and the pulse time
will not be affected. If the voltage is removed, re-applied, and then removed again before
the end of the pulse time, the Pulse Duration timer will be re-started (it will re-start each
time a voltage is removed) and the relay will continue to remain
on
until the timer expires.
-pulse relay when input changes-
When a voltage is applied to or removed from the input, the
relay will pulse for the Pulse Duration specified. If the state of the voltage changes before
the end of the pulse, the timer will be re-started (it will re-start each time the voltage
changes) and the relay will continue to remain
on
until the timer expires.
The following parameters (4-13) are available only when WebRelay
TM
is set to
Automatic Reboot
relay mode.
4. Ping IP Address:
This is the IP address that WebRelay
TM
will ping. This is typically the IP address of the device that
will be re-booted upon failure (such as a server, router, computer, etc.). It could however, be the
address of a device on the opposite side of a communications link. This is useful to auto reboot
communications devices such as CSU/DSUs, satellite modems, routers, etc..
5. Successful Ping Period:
This is the time interval (in seconds) between successful ping requests. This time can be set from 1
to 60000 seconds (1000 minutes or 16.666 hours).
6. Unsuccessful Ping Period:
When ping requests fail (no response from device), it may be desirable to begin pinging at a shorter
time interval. This allows WebRelay
TM
to determine in less time that the device is not functioning.
After each unsuccessful ping, WebRelay
TM
will wait this time interval (in seconds) before the next
ping attempt. This time can be set from 1 to 60000 seconds (1000 minutes or 16.666 hours).
7. Delay Before First Ping After Reboot:
When WebRelay
TM
is first powered, it will wait this time interval (in seconds) before beginning to
ping the device. This time delay allows the device to boot before being pinged. This time can be
set from 0 to 60000 seconds (1000 minutes or 16.666 hours).
8. Reboot Timer 1 (T1):
Pulse Time 1 (in seconds). See “Reboot Options” below for details. This time can be set from 1 to
60000 seconds (1000 minutes or 16.666 hours).
