the right arrow to select the YEAR. Use the UP and
DOWN arrow to change YEAR. Press OK when
done. Dashed line below the digits indicates selec-
tion to be edited.
8.2 Setting the POWER-ON Delay (Default 5
seconds). NOTE: This setting allows staggered
starting of Air Dryers in which there could be two
or more operating in a central office. If using an
ATS 300Plus Transfer System on a UPS backup, the
default setting of 5 seconds is okay for all dryers, as
the ATS handles the delays. A minimum of 5 sec-
onds up to 60 seconds can be set. It's recommended
that at least a 5 second separation be programmed.
There is a label located on the top cover where the
set delay may be recorded. Press MENU, arrow
down to SETUP, press OK. Select POWER-ON
Delay and Press OK. Use the UP and DOWN ar-
rows to increase and decrease the delay time. Press
OK when done.
8.3 Setting the LOW LINE PRESSURE ALARM
(Default 8 psi). Press MENU, arrow down to
SETUP, press OK. Select, LOW LINE PRESSURE
ALARM and Press OK. Use the UP and DOWN
arrows to increase and decrease the pressure. Maxi-
mum value is 25 psi in 1 psi increments. Press OK
when done.
8.4 Setting the HIGH LINE PRESSURE ALARM
(Default 20 psi). Press MENU, arrow down to
SETUP, press OK. Select HIGH LINE PRESSURE
ALARM and press OK. Use UP and DOWN arrows
to increase and decrease the pressure. Maximum
value is 25 psi in 1 psi increments. Press OK when
done.
8.5 Setting the HIGH FLOW Rate (Default 2000
SCFD above maximum capacity). NOTE: High
flow rate is not an Alarm Condition, however, can
be interpreted as a warning when reported at the
Alarm Segregation Output and is Displayed as High
Flow on the LCD Front Panel. Factory default is
set above maximum dryer capacities. It's recom-
mended before resetting this to allow the cable flow
and pressure to stabilize and set a value above what
is normal. Press MENU, arrow down to SETUP,
press OK. Select HIGH FLOW RATE and press
OK. Use the UP and DOWN arrows to increase
and decrease the flow increments of 1000 SCFD.
Press OK when done.
8.6 The Brownout Setting (Default setting disabled).
The Brownout Vol tage is fixed at 180 volt and resets
automatically at 190 volts. A Trip Delay of 2 seconds
prevents nuisance tripping upon starting. To prevent
the possibility of recycling on and off for an infinite
period, a three strike rule has been programmed. After
3 concurrent unsuccessful attempts of starting the
Air Dryer due to a brownout condition, a Brownout
Fault is displayed and a Major Alarm is issued. This
major alarm is resettable locally through the Display
or remotely through the AT S300 PLUS. To enable
the Brownout feature, Press MENU, arrow down to
BROWNOUT and press OK. Use the down arrow
and select the power-input configuration, WYE
Phase, Delta Phase, or Single Phase 180°. NOTE:
Ver ify the type of phasing provided to the dryer with
your Electrician or power group before setting the
Brownout feature. A single phase Air Dryer could
be connected to two phases of a three phase Wye or
Delta. If so, setup as Wye or Delta and not Single
phase 180°. If unknown, leave the Brownout Setting
disabled until confirmation.
8.7 Setting the AT S BUS ADDRESS (Default
A1).
Press MENU, arrow down to SETUP, press OK. Ar-
row down to select AT S BUS ADDRESS and press
OK. Use the UP and DOWN arrows to increase
and decrease the assigned address. NOTE: Values
will range from A1 through A8, B1 through B8, C1
through C8, D1 through D8, and E1 through E8.
Channels B through E are only on AT S Series with
expanded channels. Press OK when done.
NOTE: Should a SmartTech™ Air Dryer be the
last Air Dryer in the BUS Cable series connection,
the last DRYER must be configured as such on the
Alarm/ATS Interface board. A black jumper on the
board gets installed across the pins. See Appendix
A for details.
