B-TIMER (optional)
Introduction
Read operating instructions carefully before operating the
unit.
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, see chapter 4.4.5.) and
is working properly to ensure correct indication of the
filter capacity and compressor operation recognition.
Description
The B-Timer (Fig. 13) 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 fastened to the filter housing which has to be moni­
tored, 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 addi­
tion, the B-Timer can be mounted easily to any unit as an up­
grade device.
Authorized use
This unit is to be used exclusively as operating status monito­
ring device and does not release the user from additional sur­
veillance 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 P21, P31
and P41. 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.
