Notes for Model K and Model S Transfer Switches
Model K/S transfer switches equipped with Series 1000
controllers must have application software version 1.21
or higher to communicate with the Remote Annunciator.
An authorized distributor/dealer can load the latest
version of application software onto the ATS controller.
A personal computer running the ATS Setup Program is
required to configure the communication settings for
each Model K/S ATS. The Setup Program is also
needed to assign a programmable input if the generator
set fault display option is used.
The Remote Annunciator serves as a ModbusrMaster
device in the network. Only one annunciator can be
connected to the ATS or ATS network. The annunciator
and connected transfer switches cannot be connected
to any other Modbusrnetwork.
Notes for Model K1/S1 Transfer Switches
All Model K1/S1 transfer switches equipped with series
1500 controls can communicate with the remote
annunciator. The transfer switch can be configured for
communication with the annunciator using the user
interface on the transfer switch controller.
Use a personal computer running Monitor III software to
assign a unique designation to each transfer switch and
to enter load descriptions.
Note: The transfer switch designations and load
descriptions are not essential to annunciator
operation. However, if more than one ATS is
connected, transfer switch identification on the
annunciator screen will be difficult without these
descriptions. See Figure 19 and Figure 24 for
examples.
The Remote Annunciator serves as a ModbusrMaster
device in the network. Model K1/S1 transfer switches
are equipped with two (2) Modbus ports, which allow
connection of the transfer switch to two (2) Modbus
networks.
Modbus is a registered trademark of Schneider Electric.

Figure 23 Source Indicator Colors
3.3.5 Contactor Position
The letter L with the square symbol above it on the
Summary screen represents the load. A solid line from
one source symbol (N or E) to the load symbol (L)
indicates the contactor position; the load is connected to
either the Normal or Emergency source.
If there is no solid line from the load symbol to either
source symbol, then the contactor is in the Off position
(programmed-transition switches only).
If there is no solid line from the load symbol to either
source and the letter F is displayed between the source
symbols, a fault is indicated. The contactor position is
unknown. Refer to the transfer switch literature to
diagnose and correct the fault. See Figure 21 for an
example of a status screen indicating this type of fault.
3.3.6 Date and Time
The date and time are maintained by the battery-backed
