Transfer Switch Equipment
Transfer Switch — Standard and Optional Features
Transfer Switch — Standard and
Optional Features (Continued)
14D. Source 2 Present
Provides 4 Form “C” relay auxiliary
contacts. The relay is energized when
Source 2 is Present.
14E. Source 1 Available
Provides 1 Form “C” relay auxiliary
contact. The relay is energized when
Source 1 is available and within the
controller’s programmable set points.
14F. Source 2 Available
Provides 1 Form “C” relay auxiliary
contact. The relay is energized when
Source 2 is available and within the
controller’s programmable set points.
14G. Source 1 Present
Provides 2 Form “C” relay auxiliary
contacts. The relay is energized when
Source 1 is available and within the
controller’s programmable set points.
14H. Source 2 Present
Provides 2 Form “C” relay auxiliary
contacts. The relay is energized when
Source 2 is available and within the
controller’s programmable set points.
15. Switch Position Indication Contact
Provides a contact that indicates if the
power switching device is in the
“open” or “closed” position.
15E. Source 1 Position Indication
Contact
Provides 1 Form “C” contact that
indicates the position of the Source 1
power switching device.
15F. Source 2 Position Indication
Contact
Provides 1 Form “C” contact that
indicates the position of the Source 2
power-switching device.
15M. Source 2 Load Shed Contacts
Provides 4 Form “C” contacts to
initiate a load circuit disconnect while
on Source 2. This gives the user the
capability of selectively choosing not
to run certain loads while on Source 2.
35A. Pre-Transfer Signal With 1 Form
“C” Contact
Provides a signal prior to the transfer-
ring of the load. Will not transfer until
the programmable delay set point in
the controller is reached. If both sources
are not available, this option will ignore
the time delay set in the controller.
Customer Inputs
26D. Go to Emergency (Source 2)
Provides the capability for an external
contact closure to initiate a transfer
to the Source 2 power source. This
includes starting the generator, per-
forming the programmed time delays
and the transfer operation. Re-transfer
will occur when the external contact is
opened. This is a fail-safe function.
36. Load Shed From Emergency
Provides the capability for an external
NC contact to initiate a load circuit
disconnection from the Source 2 power
source. If the load circuit is connected
to Source 2 and the contact is opened,
then a re-transfer to Source 1 is
completed if Source 1 is available.
If Source 1 is not available, then the
transfer switch will transfer to neutral.
If the load circuit is connected to
Source 1 and the contact is open, then
a transfer Source 2 is prohibited.
16. Integral Overcurrent Protection
Provides thermal-magnetic overcur-
rent protection integral to the power
switching device(s). All Feature 16
options include a “Lockout” function.
If the power switching breaker trips on
an overcurrent condition, then “Lockout”
is displayed on the Automatic Transfer
Controller display and automatic oper-
ation is prevented until the appropriate
source is manually reset. On non-auto-
matic switches, a blue light is supplied
to indicate the “lockout.”
16B. Integral Overcurrent Protection
on Both Power Source Switching
Devices
Provides integral overcurrent protection
on both Source 1 and Source 2 power
switching devices.
16E. Integral Overcurrent Protection
on the Source 2 Power Switching
Device
Provides integral overcurrent protection
on the Source 2 power switching device.
16N. Integral Overcurrent Protection
on the Source 1 Power Switching
Device
Provides integral overcurrent protection
on the Source 1 power switching device.
16S. External Overcurrent Protection on
the Source 1 Power Switching Device
Provides overcurrent protection on the
Source 1 power switching device.
18. Metering
The microprocessor-based multi-
function monitoring and display features
the latest technological advances in
metering and communications
capabilities.
Available with an optional communi-
cations interface. (See Feature 48 —
Communications for available
communication modules.)
Feature 18 metering options include
all required external devices (CTs etc.)
for a fully functioning metering system.
IQ Analyzer
The IQ Analyzer is a rms sensing,
multi-function microprocessor-based
monitoring and display device with
waveform capture that provides simul-
taneous monitoring of current, voltage,
frequency, power (real, reactive and
apparent), energy (real, reactive and
apparent), demand (forward, reverse
and net), harmonics (magnitude and
phase angle), power factor and percent
THD (current and voltage).
18O. IQ Analyzer — Source 1 Line
Side Metering
Provides an IQ Analyzer for monitoring
the Source 1 line side circuit.
18P. IQ Analyzer — Source 2 Line
Side Metering
Provides an IQ Analyzer for monitoring
the Source 2 line side circuit.
18Q. IQ Analyzer With Selector
Switch for Source 1 or Source 2 Line
Side Metering
Provides an IQ Analyzer with a Source
selector switch for monitoring the
Source 1 or Source 2 line side circuit.
IQ DP-4000
The IQ DP-4000 is a rms sensing,
multi-function microprocessor-based
monitoring and display device that
provides simultaneous monitoring of
current, voltage, frequency, power
(real, reactive and apparent), energy
(real, reactive and apparent), power
factor and percent THD (current and
voltage).
18R. IQ DP-4000 — Source 1 Line
Side Metering
Provides an IQ DP-4000 for monitoring
the Source 1 line side circuit.
