Permalog 2 Deployment Instructions
1. Ensure that both the screw thread on the aerial
and the lower recessed screw hole in the Permalog are
clean, then screw the aerial into the lower screw hole
firmly by hand. Ensure that the rubber washer is fitted to
make a watertight seal (Fig 1). Remove the magnet
keeper and store for later use.
2. Start/Reset the Permalog by passing a magnet
close to, and across, the communications window. (Fig 2).
Look into the communications window to see a faint red
LED flash 5 consecutive times and then once every 5
seconds. If the LED does not flash, then pass the magnet
across the window again and look into the window to
verify.
Resetting the Permalog erases the internal memory.
Should the logger be moved from one location to another,
it must be reset to remove historical data.
This is the only way to reset the unit. Once reset, it will
operate continuously for the life of the batteries. It can only
be switched off using a Permalog interrogator unit. The
guaranteed battery life depends on factory settings. Any
medium strength magnet will reset the Permalog; for
convenience, the magnet on another Permalog may be
used (Fig 2).
Do not attempt to remove the magnet from the bottom of
any Permalog - it is loctited on and should not be removed.
3. Attach the Permalog to a metal pipe-fitting using
the magnet on the base. Always ensure that the contact
point is free from dirt so that the magnet makes a good
contact. If an eye-hook (optional accessory) is used, this
must be screwed into the top of the logger.
4. For best performance, it is recommended that the
Permalog unit is deployed in a vertical/upright position.
Only use aerials supplied by Palmer Environmental. A
right angled connector (optional accessory) is available to
enable horizontally positioned loggers to transmit signals
vertically.
Permalog units have no user serviceable parts. The
enclosure protects the user from electrical shock and other
hazards. Servicing must be referred to competent
personnel. If any unit does not appear to function correctly
then it must be returned to Palmer Environmental or an
authorised Palmer representative.
Caution: Permalog units contain batteries. There is a danger of explosion if they are
incorrectly replaced. They must only be replaced with the same or equivalent type
recommended by the manufacturer. Used batteries must be disposed of according to the
manufacturers instructions.
Redeployment
Ensure you have sufficient keepers for the magnets. Removing keepers from logger magnets
takes some effort. Always insert a piece of thin card between the keeper and the magnet to
make this job easier.
On retrieval, always grasp the main body of the logger. Do not pull loggers by the aerials.
Ensure the magnet from one logger is kept more than 3 inches (8cms) away from the window
of the nearest logger. If any magnet is held too close to the logger window, the logger
will continually reset causing an incorrect internal clock setting and subsequent
erroneous results.
An option during transport is to magnetically attach the loggers to a large piece of metal. This
will act as a keeper and prevent the loggers from moving.
