7.0 OTIONS
7.1 POWER OUTAGE RESTART OPTION
For customers that have interruptions in their incoming
power supply to the compressor and must maintain an
uninterrupted supply of compressed air, the Power
Outage Restart Option allows an Intellisyscompressor to
restart automatically 10-120 seconds (adjustable) after
incoming power is restored.
The Power Outage Restart Option is turned on by
plugging in the required option module and enabling it
thru the OPTION’S set point routine. The restart time
delay, which is adjustable from 10-600 seconds, can also
be adjusted while in the option’s set routine on the
Intellisys controller. Any time power is restored to the
compressor after a power interruption, a horn located on
the side of the starter box will sound during the restart
time delay (10-600 seconds), after which the compressor
will automatically start. After starting, the compressor will
return to the mode of operation that the compressor was
in prior to the power interruption.
This option may be factory installed or a field installation
kit is available.
7.2 SEQUENCER
The sequencer option is turned on by enabling it through
the OPTIONS set point routine. Enabling this
option will allow the compressor to be controlled by an
external device, such as an ISC or sequencer, using
the communications port (P7) on the Intellisys.
7.3 LOW AMBIENT
The lowambient option is turned on by enabling it through
the OPTIONS set point routine. Also temperature sensor,
3CTT, is added to the compressor and connected at P6-7
& 8 on the Intellisys. The options set point, minimum
cooler out temperature, is set to the minimum temperature
at which the unit can load. When this option is enabled,
the compressor, after being started, will not load until the
Intellisys reads a temperature from 3CTT at or higher
than the value of the minimum cooler out temperature set
point. If this option is enabled without installing 3CTT,
a SENSOR FAILURE 3CTT alarm will occur.
7.4 SEPARATOR DELTA-P SOLENOID
The separator delta-p solenoid option is turned on by
enabling it through the OPTIONS set point routine.
When this option is enabled, the Intellisys will measure
the pressure drop across the separator element by
first reading the wet side sump pressure. Next the
Intellisys will momentarily energize solenoid that will
switch the dry side sump pressure to the sump pressure
sensor (3APT). The Intellisys will then read the dry
side sump pressure and subtract it from the wet side
sump pressure to measure the pressure drop across the
separator element. Do not enable this option if the
separator delta-p solenoid is not installed.This will
result in an incorrect measurement of the pressure
drop across the separator element.
7.5 SEPARATOR DELTA-P SENSOR
The separator delta-p sensor option is turned on by
enabling it through the OPTIONS set point routine.
When this option is enabled, the Intellisys will measure
the pressure drop across the separator element by
subtracting the dry side sump pressure (6APT) from the
wet side sump pressure (3APT). Do not enable this
option if the separator delta-p sensor is not installed.
This will result in an incorrect measurement of the
pressure drop across the separator element and a
6APT sensor failure warning.
7.6 HIGH DUST FILTER
The high dust filter option is turned on by enabling it
through the OPTIONS set point routine. If this option
is enabled, the Intellisys; will change its measurement of
the inlet filter. Do not enable this option unless a high
dust filter is installed.
7.7 LEAD/LAG CYCLE LENGTH
The lead/lag cycle length option allows the Intellisys to
automatically switch the online and offline pressure
settings to the lead or lag values after a programmed
number of hours.This option is enabled by selecting a
number of hours greater than 0 in the OPTIONS set point
routine.
7.8 SCHEDULEDSTART/STOP
The scheduled start/stop option allows the customer to
automatically start and stop the compressor once each
day, based on the real time clock. This is an installed
option and is enabled by selecting a scheduled start and
scheduled stop time. Setting the scheduled start and
scheduled stop times to the same value will disable this
option.
