01H Aux Relay Timing:
This setting delays the automatic closing and
opening of the Aux Relay contacts after the
Relay Open
and
Relay Close
settings have been satisfied.
Close Delay
- Use this setting to delay the close of the Aux Relay contact
once the Voltage Trip point has been reached. This sets a hysteresis so
the Aux Relay does not cycle unnecessarily. Range is
0-240 seconds
Open Delay
- Use this setting to delay the opening of the Aux Relay
contact once the Voltage Trip point has been reached. This sets a
hysteresis so the Aux Relay does not cycle unnecessarily. Range is
0-
240 seconds
Default settings
-
Close Delay
and
Open Delay: 10 seconds
Auxiliary (Aux) Relay
The router contains a 2-wire dry contact Aux Relay. The Aux Relay can be
manually opened or closed, or is voltage driven and can be set to either close
on low DC voltage and open on high DC voltage, or to close on high DC voltage
and open on low DC voltage. The relay can be set to the
Auto
position where
it will read the open and close voltage settings with delay times, or it can be
manually either forced closed or open.
What is the Aux Relay used for?
The most common use is to turn on an
exhaust fan to eliminate your battery bank gasses using the VDC start and
stop settings. The Aux Relay can also be used to control the coil of a current
carrying relay.
How do I adjust the Aux Relay?
The three menus used to adjust the Aux
Relay are the
01F Aux Relay State
,
01G Aux Relay V Trip
, and
01H Aux Relay
Timing
menus. These three menus are used to select the operating state of the
Aux Relay (menu
01F
), the DC voltage at which the Aux Relay automatically
opens and closes (menu
01G
), and the delay timing on open and closing of
the Aux Relay (menu
01H
).
Aux Relay LED
-
The Aux Relay LED will illuminate in an amber color if the
relay is active (closed) in the programmed state.
Example:
The Aux Relay is set to
Auto
in menu
01F
. The
01G Aux Relay V
Trip’s Relay Close
setting is 12.0 VDC and the
Relay Open
setting is 14.5
VDC. The
01H Aux Relay Timing
menu’s
Close Delay
and
Open Delay
set-
tings are
10 seconds.
When the battery voltage reaches 12.0 VDC after a 10 second delay, the
Aux Relay will close and the LED will illuminate amber. When the battery
voltage reaches 14.5 VDC after a 10 second delay, the Aux Relay will open
and the Aux Relay LED will turn off.
