Discrete Input 2 Selectione:
Configures the use of Discrete Input 2. The
options are
Not Used
,
Fan Fail
, and User
Defined
.
Fan Fail
may be used with an airflow sensor or micro switch connected to
ventilation louvers to indicate when the fan is operating properly.
User Defined
may be used with a wider array of external sensors or
switches to generate an alarm or trip condition, control the fans, or even
control other equipment using the Fan2 relay
Default is
Not Used
.
Discrete Input 2 Edgee:
This option should only be set after the Discrete
Input 2 Selection is changed from
Not Used
. The options differ depend-
ing on the Discrete Input 2 Selection.
For
Fan Fail
the options are
Open
or
Closed
and configure the input
state that indicates a fan failure. This allows connection to either normally
closed or normally open contacts. The default is
Open
.
For
User Defined
two options are given to define the relationship
between the input state and output state. The options are
Direct
, which
means a closure on the input results in a closure on the output, or
Invert
which means an open on the input causes a closure on the output. This
allows the use of normally open or normally closed contacts on the input.
The default is
Direct
.
Discrete Input 2 Effecte:
This option should only be set after the Discrete
Input 2 Selection is changed from
Not Used
. The options differ depending
on the Discrete Input 2 Selection.
For
Fan Fail
the options are
Alarm Only
or
Alarm + Fan 1
. The default is
Alarm Only
. Selecting either option will activate an alarm condition when
a fan failure is detected, activating the alarm relay and front panel LED,
and if enabled displaying
A. AIR-ND
(airflow not detected). The second
option can be used to configure Fan 2 as a backup to come on if FAN 1
fails.
For
User Defined
the options are
Alarm
,
Trip
,
Fan2
,
Fans ON
, and
Fans
OFF
. The default is
Alarm
. The Fans ON and Fans OFF control both fans
and override temperature setpoints, thus they can be used to always force
fans On or Off.
