hr, the user may limit the unit to 80 lb/hr by setting this
to 89%.
• Low Hum. – This allows the operator to trigger a low
humidity alarm if the control humidity falls below a
certain value.
NOTE: Some units may be configured with High Limit
humidistats in lieu of proportional high limit devices. If the unit
is using a humidistat for the high limit device, the setpoints
menu will only contain Humidity SP and Low Hum. The other
items do not pertain to high limit humidistat operation.
Alarm Screen
The Alarm Screen allows the operator to check the status
of the system alarms. This screen can scroll through the
currently active alarms; as well as alarm conditions that have
returned to normal. The date/time of the alarm is recorded
when the alarm goes active and when the alarm returns to
normal. Some alarms will lock out the unit and will require a
manual reset. This is performed by turning the unit ON/OFF
switch to the OFF position, waiting until the red LED goes out,
and then returning the switch to the ON position. Timed Drain
operations will illuminate the alarm LED. The drain will show
up as an active alarm while the unit is draining and return to
normal upon completion of the drain cycle. This allows the
control system to date/time stamp the drain operation so the
user may refer to it if needed. Upon completion of the timed
drain the unit will return to normal operation.
Clockset Screen
The Clockset Screen allows the user to adjust the system
clock. Time is only used for logging alarm times, so accurate
system time is not critical to proper system operation. The
DST link on this screen allows the user to set-up the day-light
saving time start and stop dates. It is recommended that the
date/time be set and confirmed before operating the unit.
UserPW Screen
Upon attempting to change parameters or set-points, the
control system will prompt the user for a password. The
USER password is 1111 by default. Logging into the keypad
as the USER will allow any of the items in the Parameters
Menu or the Set-points Menu to be changed by the user. The
CONFIG menu is typically for factory use only and should not
be modified by any operator without guidance from factory
technical personnel or a factory trained service technician.
If the ADMIN has logged into the system he may set a new
user password. The ADMIN password is 2222 by default.
Again, items in the CONFIG menu should not be changed by
untrained personnel.
Config Screen
The Configuration Screen allows the operator to adjust
system parameters that the typical operator usually would not
need to adjust under normal circumstances. The unit type
may be selected as P or I. A “P” unit operates according to
