6. IQT Actuator Failsafe Settings.
The actuator can be operated by
standard remote control signals (open/
close/interlocks/ESD) under AC supply
control.
On AC supply loss, the actuator will
automatically perform an ESD using
battery power.
For the required failsafe operation,
using the supplied Infra-red Setting
Tool, set configuration functions [A1],
[A2] and [A4] for the desired failsafe
action. Refer to page 32, [A1] ESD
Action, [A2] ESD contact type and [A4]
ESD override interlocks actuator settings
must be checked and/or set .
Switch ON AC supply power to the
IQT actuator. Refer to table below for
settings.
NOTE. If network option cards are used
with a failsafe setup the auxillary input
masks [PF] must be set accordingly. The
ESD setting in the mask must always
be set for NO (normally open) type. For
example if only the ESD is required for
an auxillary input, the setting would be
80 (hex). See section 9 configuration
settings. Ensure the remote control
source option [Od] is set to [oP].
NOTE. If ESD is being used for AC
supply control the user must decide
if ESD is to override local stop. If ESD
override local stop is required set [A5]
to [NO].
Testing
To test the failsafe function, switch off
AC supply to IQT actuator. Actuator will
perform the set failsafe function.
Refer to page 63.
