Bauer B-Timer Operating Instructions

Introduction
Read the operating instructions carefully before operating the
unit. (Applicable for units from version 300.301.811 up).
The settings in the setup menu are essential
for the correct indication of the filter capac­
ity. Without correct settings, the B-Timer can
be used as an hourmeter, only!
Make sure that the pressure maintaining
valve of the compressor is adjusted to 150 bar
(factory setting) and is working properly to
ensure correct indication of the filter capacity and com­
pressor operation recognition.
Make sure that all maintenance counter
(a+b+c) were reset directly before the
delivery. (Otherwise storage times would be
taken into account and wrong maintenance intervals are
displayed on the B-Timer.) If no reset of the maintenance
counters has been done, you are obliged to reset them.
Refer to Reset on page 4.
Description
The B-Timer (Fig. 1) is a self-activating mini-computer that
counts the operating hours of the compressor and calculates
the saturation of the filter cartridge from time, temperature,
cartridge type, and delivery rate of the compressor. It displays
operating hours, cartridge lifetime, and all maintenance due for
the compressor. The B-Timer does neither need external power
nor any other connection to the pressure system. It is simply fas­
tened to the filter housing which has to be monitored, by means
of a clamp, and is therefore the ideal filter control device for all
mobile compressor units, especially for portable petrol or diesel
driven scuba diving models. In addition, the B-Timer can be
mounted easily to any unit as an upgrade device.
Authorized use
This unit is to be used exclusively as operating status monitoring
device and does not release the user from additional surveil­
lance and testing of the breathing air quality of the filter system
according to national standards (e.g. EN 12021). With the B-
Timer, this is not possible!
The B-Timer may only be used with the filter systems specified
above, it cannot be used on Verticus and Mini-Verticus com­
pressor units. The respective filter cartridge numbers are stored
in the software. Other use is strictly prohibited. The manufac­
turer and the supplier void all responsibility for risk, damage or
injury resulting from failure to follow these instructions.
Observe the operating limits of the unit:

Mounting
Mount the B-Timer with the supplied clamp in the center of the
golden filter housing, on P41 filter system at the grey purifier
housing. It has to have contact to the housing with both straps
of the back plate. Make sure not to touch other mounting
clamps of the filter. Should the B-Timer have to be re-mounted,
e.g. when changing the filter housing, ensure that the tempera­
ture pad on the back plate is not damaged.
