5.9 Connection in a Series Circuit
5.9.1 Operational characteristics
The extent of use of all RELIANCE IQ functionality is determined by the application. All functionality described in this
document is not necessarily used at a specific installation. This section is a summary of common functionality available in
RELIANCE IQ.

5.9.2 Power On or Default State
IQ is configured to set the lamp to a predefined state when the series circuit is energized. This feature is called default state
and the options are LAMP ON, LAMP OFF or LAMP FLASHING. The option to select depends on the light function for a
RELIANCE IQ fitting and the operative requirements.
5.9.3 Safe State
In case communication between the RELIANCE IQ and the SCM is interrupted or lost, IQ functionality will after a
programmable timeout set the lamp to a predefined state known as safe state. Safe state can be set to LAMP ON, LAMP OFF,
LAMP FLASHING or no change.
5.9.4 Command memory
When current in the series circuit is lost if a CCR is turned off or for any other reason, RELIANCE IQ remembers the current
lamp status for a limited amount of time. The IQ can be configured to, once current is restored in the circuit, set the lamp to
the remembered state, typically the last commanded state before a power loss. This feature, when enabled, overrides the
default state.
It is possible to apply a condition based on the amount of time current was lost. The RELIANCE IQ sets the lamp to default
state if current was restored beyond this time limit. The time limit is programmable from approximately 1-20 seconds.
5.9.5 Soft ON/OFF
The RELIANCE IQ can be programmed to delay the physical turn on or turn off of the lamp upon reception of a command
from the SCM. The feature is called SoftON/SoftOFF and its purpose is to mitigate the sudden load change to which the CCR
is subjected when a large portion of the load is commanded on or off with a single command. The command acknowledge
from the RELIANCE IQ is not affected, and thereby neither the response time. Without this feature it may not be possible to
turn on or off all or most lights on a circuit with a single command without the CCR tripping either because of over- or under-
current.
The physical delay is programmable on an individual level in 10ms increments. There is no response time impact when
SoftON/SoftOFF is enabled.
5.9.6 Sequenced flashing
RELIANCE IQ can be used to create different types of “running rabbit” patterns on the series circuit.
