If power is lost to the Addressable Relay II it will
power-up in the de-energized (OPEN) state.
4.5 RELAY OUTPUTS
As described in Section 2, the rear access area pro-
vides for access to all output connections. Refer to
Figure 2-3 for a graphical representation and position of
all output connections. The relay functions are divided
into two categories:
• Customer Connections
• Transfer Operation Contacts
4.5.1 CUSTOMER CONNECTIONS
S2 Generator
This latched coil relay provides a Form A contact on Pins
1 and 2 of Connector J5. The relay is the generator start
relay for system configurations employing a generator on
the input source designated Source 2.
S1 Generator
This latched coil relay provides a Form A contact on Pins
3 and 4 of Connector J5. The relay is the generator start
relay for system configurations employing a generator on
the input source designated Source 1.
Alarm
This Form C relay is used to indicate an alarm condition.
The full Form C contact of this relay is implemented with
Common Pin 8, Normally Closed Pin 7, and Normally
Open Pin 6 of Connector J5. The relay is normally de-
energized to indicate the absence of an alarm state.
Energization of the relay indicates the presence of an
alarm condition. Alarm conditions include improper
circuit breaker operation, motor operator failure, and
unsuccessful in-phase transition. An alarm may be reset
by simultaneously pressing the Increase and Decrease
Pushbuttons.
S2 Available
This Form C relay is used to indicate the availability of
Source 2. The full Form C contact of this relay is imple-
mented with Common Pin 11, Normally Closed Pin 10,
and Normally Open Pin 9 of Connector J5. This relay
essentially duplicates the Source 2 available status LED
meaning that the setpoint criteria has been met.
4.7 PROGRAMMING MODE
IQ Transfer is fully programmable from the device’s
faceplate once the Run/Program switch on the rear of
NOTICE
S1 Available
This Form C relay is used to indicate the availability of
Source 1. The full Form C contact of this relay is imple-
mented with Common Pin 14, Normally Closed Pin 13,
and Normally Open Pin 12 of Connector J5. This relay
essentially duplicates the Source 1 available status LED
meaning that the setpoint criteria has been met.
4.5.2 TRANSFER OPERATION CONTACTS
K1, K2, K3 and K4 are factory wired to operate the
transfer switch. No customer wiring is to be done.
4.6 TEST MODE
The Test Mode is intended to permit the periodic perfor-
mance of tests of the system. To enter the Test Mode,
the display window must be blank.
When the Engine Test Pushbutton is pressed and
released, “START” will be shown in the display window
and the Status LED will be lit. At this point, if the initia-
tion of a test is not desired, pressing the Increase and
Decrease Pushbuttons simultaneously will clear the dis-
play window. In addition, if any of the display pushbut-
tons are not touched for 2 1/2 minutes, the Test Mode
and Display Window would be cleared. If a test is
desired, the Engine Test Pushbutton must be pressed a
second time before the 2 1/2 minutes have expired. At
this time the Status and Test Mode LEDs are lit red, and
one Test Mode cycle is implemented.
The exact test conditions are determined by pro-
grammed setpoints. Whether or not to transfer the load
during testing, disable the engine test completely, and
the engine test run time are operator selected parame-
ters. Refer to Section 5 Programming and specifically
Table 5.1 for test programming details.
A load transfer test cycle includes a full generator start,
a transfer, and a re-transfer. For the test cycle to pro-
ceed, the Normal Source must be available. The test
cycle will be aborted if the Emergency Source does not
become available within a set time-out period, or if a
needed source becomes unavailable. In addition, the
test will be aborted if the Test Pushbutton is again
pressed and released. Both LEDs turn off upon the suc-
cessful completion of a test cycle, once the time delay
engine cool down timer has expired and the generator is
stopped.
If the “Number of Generators” setpoint is programmed
to zero, the Engine Test Pushbutton is not functional.
If the setpoint is programmed to two, the test will be per-
formed on the generator not connected to the load.
