7.3.8 Write Protect
Hardware write protection and software write
protection functions are available for FN310.
Hardware Write Protection
Hardware Write Protection is set by slide switch on
the front panel back.
Software Write Protection
Software Write Protection is set by the parameter
of software write protect of UAP Option in UAPMO
block.
For the relationship between hardware write
protection and software write protection, refer to
subsection 9.1.10 “Parameter Summary”.
7.3.9 Switching to the Deep Sleep Mode
When the FN310 will not be used for a long time,
switch the FN310 to the deep sleep mode to
conserve battery power. There are two methods
of switching to the deep sleep mode. To switch to
deep sleep mode, follow the procedure below.
Magnet Switch Operation
Procedures for switching to the deep sleep mode
using a magnet switch are as follows.
1. Touch the magnet switch 1 for 5 seconds by a
magnet (LCD displays “SLEEP” flashing).
2. Touch the magnet switch 1 for an additional 5
seconds by a magnet (LCD displays “SLEEP”).
3. Touch the magnet switch 2 within next 5
seconds by a magnet.
Write Parameter
TRANSDUCER block: Special Cmd
Set deep sleep mode to Special Cmd parameter.
There are three methods to start from the deep
sleep mode.
Restart
Restart by re-connection of the battery pack.
Infrared Communication
Start by receiving infrared communication. Use the
wireless field device configuration tool (for infrared)
or device provisioning tool.
Magnet Switch Operation
Start by touching a magnet to magnet switch 1 for
10 seconds.
CAUTION
After setting the deep sleep mode by infrared
device configuration tool, keep the infrared port
of device away from any other infrared signals.
NOTE
•
After switching to deep sleep mode,
the FN310 stops any field wireless
communication. For this reaon, there is the
case that an error is display on field wireless
configuraiton tool.
•
To wake up from deep sleep mode by
reconnection of battery pack, please pull
battery pack and wait more than 30 seconds
before attaching battery pack.
7.3.10 Switching to the Silence Mode
This is a function to pause the FN310 when it
cannot join the field wireless network after a
specified time has elapsed. This function is effective
in conserving battery power when, for example,
the installation of the Field Wireless Integrated
Gateway is delayed compared to that of field
wireless devices. When the FN310 fails to search
the network for about 120 minutes, it switches to
silence mode automatically. Thereafter, a cycle
of 18 minutes pause and 36 seconds search is
repeated until the FN310 can join the field wireless
network. To minimize the consumption of the
battery, the FN310 turns off the integral indicator
and stops the measurement.
To start from the silence mode, either removes
and inserts the battery pack, or receiving infrared
communication. Use the device configuration tool
(for infrared) or device provisioning tool.
