8. Options and Setpoints
The options and setpoints are stored in non-
volatile memory. A standard option is
enabled on every controller. Those
designated as programmable can be added
at the factory at the customer’s request
(usually at an additional cost), or can be
added in the field via PC software and/or an
option key. Setpoint values are modified by
using the pushbutton keys on the front panel
or using the Cutler-Hammer ATS-Connect
Field Update software.
NOTICE
REFER TO BOTH THE FACTORY TEST
SHEET, AND THE DRAWINGS THAT
SHIPPED WITH THE TRANSFER SWITCH
TO DETERMINE THE OPTIONS THAT
ARE INSTALLED. AN OPTION WILL NOT
BE FUNCTIONAL, NOR WILL THE
PARAMETERS BE ADJUSTABLE
THROUGH THE SETPOINTS MENU IF AN
OPTION IS NOT ENABLED
.
8.1 MP1 Series Controller
Options
Standard option - TDNE
Time Delay Normal to Emergency
Provides a time delay when transferring the
normal source to the emergency source. To
ensure stability of the emergency source.
Timing begins when the emergency source
becomes available.
Standard option - TDES
Time Delay Engine Start
Delays the initiation of the engine start
circuit in order to override momentary power
outages or voltage fluctuations of the normal
source. The TDES timer shall start when
the normal source becomes unavailable. If
the normal source becomes available while
timing, the TDES timer shall reset. The
controller can perform the time delay engine
start function without control power for 120
seconds.
Standard option - TDEN
Time Delay Emergency to Normal
Delays the transfer from the emergency
source to the normal source to permit
stabilization of the normal source before re-
transfer is made. Timing begins when the
normal source becomes available.
If the emergency source fails during timing
for a period greater than 0.5 seconds,
transfer to normal source is immediate. If
the normal source fails during timing, the
TDEN timer shall reset once the normal
source becomes available again.
Standard option - TDEC
Time Delay Engine Cooldown
Permits the generator to continue to run
unloaded after retransfer to the normal
source has occurred. Timing begins when
the transfer to normal has been completed.
Emergency Source Frequency/Voltage
Sensing
Continuously monitors the emergency
source for one of the conditions listed below.
When the emergency frequency and/or
voltage is outside the dropout setpoints, the
source will become unavailable. The
source’s frequency and/or voltage will then
have to be within the pickup setpoints to
become available again.
a) Emergency Source Undervoltage
(Standard option
)
b) Emergency Source Underfrequency
(Standard option)
c) Emergency Source Overvoltage
(Optional Feature)
d) Emergency Source Overfrequency
(Optional Feature)
Normal Source Frequency/Voltage
Sensing
Continuously monitors the normal source for
out of range setpoint values. When the
normal frequency and/or voltage is outside
the dropout setpoints, the source will
become unavailable. This will then prompt a
transfer to the emergency source once it
becomes available. The normal source’s
frequency and/or voltage will then have to
be within the pickup setpoints to become
available again for a retransfer.
a) Normal
Source
Undervoltage
(Standard
option)
