2.5.5 Real Time Clock & Calendar
The iRIS has a non-volatile real time clock that can be set by the user via a terminal session.
2.5.6 Security
The iRIS can be configured with a PIN code to prevent unauthorised access to restricted information through
the LCD and keypad. When a user is logged on, the totalisers can be reset via the keypad or a terminal
session. When the unit is locked, the totalisers can only be reset via a terminal session.
The PIN code is configured via a terminal session. See Option 7 in Section 5.3.10.
3 Installation
3.1 Recommended Deployment Procedure
3.1.1 Prior to site visit
If possible, configure the iCE
3
completely before taking it into the field for installation. Use the typical
configuration examples below as a guide. After configuration, when the battery is removed again
prior to installation, all configuration settings will be retained with the exception of the date and time
and data logging pointers. These are set as part of final commissioning.
3.1.2 Installation on site
Remove the enclosure lid by removing the four screws from the corners.
Mount the enclosure base in the desired location using suitable screws through the two mounting
holes in the base side walls.
Remove the rubber sealing plug from one or both glands. Feed the connection cable(s) through the
glands, but do not tighten the glands yet.
Terminate any instrumentation first (water meter reed switches, level sensors etc) before connecting
the datalogger. DO NOT LIVEN ANY POWER SUPPLIES YET.
Strip the cable ends and trim the wire ends for connection into the terminals. If the cable is shielded,
ensure that loose shield wire ends are covered with heatshrink tube to prevent short circuits.
Terminate the wire ends into the appropriate connectors. Note that the terminals are small and care
should be taken to avoid excessive bare wire lengths or loose strands being exposed.
Check the settings of the analogue input and digital input jumpers and set them appropriately. Refer
to Sections 4.2.3 and 4.2.4 for details on these.
Adjust the amount of cable inside the enclosure to enable the lid to be fitted easily without jamming.
Tighten the glands.
Install the lithium battery, ensuring it is installed the correct way round. The logger should start.
Secure the lid with the four screws. Apply external power if used (battery or d.c supply)
With a laptop, set the time and date and also test that all sensor values are correctly scaled and
working.
Initialise the logger which will reset pointers and totalisers. See Option 1 in Section 5.3.8
Allow the logger to log at least a few samples. Unload the data and check it is correct.
