Apply Power To The 854 Atg - Honeywell 854 ATG Series Instruction Manual

How to program?
When the 847 PET is plugged into the 854 ATG and the instrument is powered, the PET can be switched on.
By operating the keyboard, items can be requested and settings can be changed.
For example:
Item (+ setting)
(typing in on PET keyboard)
RL <enter>
W2=ENRAF2 <enter>
RL=+012.3400 <enter>
EX <enter>
Recommended programming sequence
The 854 ATG is already pre-programmed at the factory. However, several parameters, application depended,
must be programmed at commissioning.
Step 1 Start with programming / checking of the format depended items (refer to section 3.3.3)
Step 2 Proceed with programming / checking of the items for the standard level measurement without
optional functions (refer to sections 3.3.4 to 3.3.7).
Step 3 Check with the identification code on the label of your 854 ATG whether the gauge is equipped with
one or more optional functions, and program the items for that options (refer to the appropriate
option manuals).

3.3.2 Apply power to the 854 ATG

To program the gauge, power must be switched on. That should be done in this stage.
Note:
After the initialisation of the gauge, the displacer is moving down, because the default level setting is at 26
metres.
If the displacer movement is unwanted in this stage, issue the FR command by the PET. This action freezes
the displacer position. This command must be repeated after each EX (exit) or RS (reset) command.
The freeze command can be cancelled by the UN (unlock) command.

Description
Request for the current value of item RL (reference level).
The reply on the PET display will be: RL+000.0000
This means: the reference level is: 0 metres.
Enter protection level 2 (default level 2 password is: ENRAF2).
Give the required setting for the reference level
(here, as an example: 12.34 metres).
Exit protection level 2.
The 854 ATG will now initialise and the new entered value of the
reference level will become active after the re-start.
