Installation
Care should be taken to avoid the load discharging the internal and/or external 12V battery. Ensure
adequate power supply charging capacity is available to cater for the demands of both the iRIS and load.
The digital outputs may also be programmed to follow the state of the IP connection so that they will be active when a
wireless IP session has been established. This mode can be used to control power to an external data radio when using the
iRIS as a radio-based gateway.
Typically, an output is configured to follow a schedule for use in powering loads. There is a similar mode termed
"Schedule Plus".
In "Schedule Plus" mode, the relevant output(s) will be activated when a user is logged on to allow sensor
calibration or radio communication testing.
Alternatively, they can be selected for remote control directly from a HydroTel™ base station, activation if any alarm is
active in the iRIS or to operate in response to absolute set points against the current sensor value on Sensor #1 for
applications such as triggering sediment samplers.
See section
for details on the digital output modes.
