Increase or Decrease keys. Once all of the
setpoint operating parameters have been
entered, the user may save the new setpoint
options by depressing the Save (Exit) key.
Once this is completed, the controller
acknowledges the setpoint values have
been programmed by displaying the
message “
Setpoints Programmed
.”
6.3 Lamp
Test
(Increase and Decrease Simultaneously)
Pressing the Increase and Decrease buttons
simultaneously will cause the all LEDS to
illuminate for a minimum of ten seconds.
During this lamp test the LCD displays the
message “Lamp Test.”
6.4 Serial
Connection
A serial input connection is accessible from
the rear of the ATS-MP1 controller. This
input is used for factory and field
programmability of options and setpoints. It
communicates to a standard PC or laptop
via serial communication. A field update
software package for Windows
based PCs
is available. This software allows the user to
adjust and view controller setpoints, and add
additional options to the controller with a
factory authorized code. Contact Cutler-
Hammer for further details.
6.5 LED
Outputs
Normal Source Available
This red LED is lit when the normal source
meets the user programmed setpoint
criteria.
Normal Source Connected
This red LED displays the status of the
transfer switch position. It illuminates when
the normal source is available and the
transfer switch is in normal position.
Indication of the transfer switch in normal
position is accomplished by sensing the
closed A-contact of the normal breaker
auxiliary.
Emergency Source Available
This red LED is lit when the emergency
source meets the user programmed setpoint
criteria.
Emergency Source Connected
This red LED displays the status of the
transfer switch position. It illuminates when
the emergency source is available and the
transfer switch is in emergency position.
Indication of the transfer switch in
emergency position is accomplished by
sensing the closed A-contact of the
emergency breaker auxiliary.
6.6 Input Contact Descriptions
The control outputs of the ATS-MP1
controller are wetted DC contacts.
Source 1 Auxiliary Closed
This contact is hard-wired to the normal
breaker auxiliary contact that is closed when
the normal breaker is closed (A-contact).
Source 2 Auxiliary Closed
This contact is hard-wired to the emergency
breaker auxiliary contact that is closed when
the emergency breaker is closed (A-
contact).
Source 1 and Source 2 Lockout
(Requires Option 16)
This contact is hard-wired to the normal
and/or emergency breaker lockout (bell
alarms) contacts that close when one of the
breaker has tripped due to an overcurrent
condition or fault current condition. Closure
of this contact inhibits any transfer from
occurring and the message
“*** LOCKOUT ***” will appear on the LCD.
Bypass Time Delay(s)
(Requires Option 8)
Closure of this contact will bypass the
programmed values for either or both of the
TDNE and TDEN timer setpoints, depending
upon which option has been selected
Go To Neutral
(Services Disconnect)
Closure of this contact forces the controller
to switch to the neutral position thereby
disconnecting the load from both sources.
Enabling of this function forces a minimum
neutral position time as determined by the
programmed TDN setpoint.
Test/Area Protection
Closure of this contact will cause the
controller to initiate a transfer to Source 2 if
the transfer switch is in Source 1 position.
Opening of this contact will cause the
controller to initiate a transfer to Source 1 if
the transfer switch is in Source 2 position.
