OPERATING INSTRUCTIONS (XE-70M CONTROLLER)
These pages are used for setting parameters that are
specific to the compressor�� All of the factory settings
that are adjustable are listed below�� All settings on these
pages are password protected��
Rated Pressure (psi – 100, 115, 135, 190) – This is the
nominal pressure that the compressor can provide��
Starter Type (Star-delta, Remote Starter, Soft Starter)
– Choose the starter type installed in the compressor�� If
this is not set correctly, the compressor may not start��
Service Level (0, 1, or 2) – Set the service level reminders
for the compressor��
Service Level 0 – Disables all service reminders
•
Service Level 1 – A service warning will be issued
•
when the service time period has been expired�� This
warning can be reset by any user��
Service Level 2 – A service warning will be issued
•
100 hours prior to the service time period expiring��
This 100 hour warning can be reset by any user�� At
the expiration of the service time interval the service
warning will again occur�� This warning can be reset by
any user but will recur every 24 hours until the service
complete factory setpoint has been set (Password
Required)��
Motor Protection – Used to enable current transformer
based overload and locked rotor protection�� This must
be set to ON unless a thermal overload is installed in the
compressor starter panel��
Nominal Current – Used to set up the motor overload
protection�� This value is set at the factory and must not
be changed��
Main Motor CT Range - Must match the range of the
installed current transformers�� All current transformers
must have the same range��
CT Windings – Must match the number of windings
of the installed current transformers�� All current
transformers must have the same winding number
Enable Modulation (ON/OFF) – This enables the
modulation option in the controller, allowing Modulation
or Mod/ACS modes of operations to be chosen from
the operator settings�� The modulation option must be
installed on the compressor for this to work��
Enable PAC (ON/OFF) – Enables Progressive Adaptive
Control – this will reduce operating pressure in the case
of a Change HE Filter warning or High Sump Pressure
warning in order to protect the compressor��

Enable Dryer (ON/OFF) ( Option not applicable for UP
Series�� Set to defaults) – Enables dryer control from
the controller�� The dryer option must be installed in the
compressor for this to work properly��
Constant Run Dryer (ON/OFF) ( Option not applicable
for UP Series�� Set to defaults) – Enabling this function
causes the dryer to run whenever the compressor is in
a running state, including auto-restart�� Disabling this
will allow the dryer to stop if certain conditions are met,
such as satisfying a minimum run timer�� Certain dryer
warnings will stop the dryer regardless of this setpoint��
If the dryer stops for any reason it will not be allowed to
restart for 90 seconds�� When the compressor is being
controlled by an external source, constant run dryer will
be enabled regardless of this setpoint's state��
Enable VSD Blower (ON/OFF) ( Option not applicable
for UP Series�� Set to defaults) – Enable this function if
there is a VSD blower option installed in the compressor��
Limit Blower VSD (ON/OFF) ( Option not applicable for
UP Series�� Set to defaults) – Enable this setpoint to limit
the maximum speed of the blower to 39 Hz��
Blower Override ( Option not applicable for UP Series��
Set to defaults) – Sets the blower on VSD blower
equipped units to run at a set percentage of full speed��
Setting this to 101% enables automatic control
Enable Low Ambient (ON/OFF) ( Option not applicable
for UP Series�� Set to defaults) – Enable this setpoint
to activate low ambient control�� Low ambient control
uses temperature readings to determine the speed of
the blower to allow the compressor to reach an optimal
operating temperature�� When low ambient is enabled,
the compressor will always start, but will run unloaded
until the airend discharge temperature reaches the low
ambient temperature set point��
Running Hours (adjustable) – Used to adjust the
running hours counter on the compressor
Loaded Hours (adjustable) – Used to adjust the loaded
hours on the compressor
Power ON Hours (Read Only)
