screen, the error and its correction have to be confirmed by pressing
the START/SET key.
3 Operation
Caution
Be sure that all provisions of Sect. 1.1 and 1.2 above are strictly
complied with for both the installation and the operation. Failure
to do so may expose you to hazardous situations.
3.1 Normal Operation and Error Alert
When it works normally, the unit shows the so-called standard display
(see Display 1) after it was switched on. The standard display shows
the outside temperature, the detected power supply, and the date and
time.
In case of an error condition, the reason for it is displayed. The example
of Display 2 hints at a low voltage condition or power supply failure. An
“Exhaust Air Error” may also be displayed. This error indicates another
restriction, which is mechanical in most cases, of the flow of the fluid.
(See Sect. 3.7 for messages relevant to the air filter unit.)
After an error was cleared, the unit indicates that the exhaust airflow has
returned to normal. Still, the error and its successful correction have yet
to be confirmed by pressing the START/SET key (see Display 3).
3.2 Configuring the Settings
Pressing the
and
keys simultaneously opens the configuration menus
of the exhaust airflow monitor in which its parameters can be adjusted
to your particular ways of operating the unit.
The 3 configuration menus are presented hierarchically and every level
is accessible from the immediately lower level in the hierarchy. Whenever
an operator wants to access one of the menu levels, either by using the
above keypress combination or from the lower menu level, the airflow
monitor requests entering an access code. The configuration options that
are relevant for the operator are found on the two menu levels explained
below (Configuration Menu 1 and Configuration Menu 2). Access to the
hierarchically highest menu level, the so-called Supervisor Menu, is
restricted to specifically trained technical staff.
When a menu is accessed, the access code applicable to the menu level
in question is entered using the four arrow keys. After its input, the code
has to be confirmed by pressing the START/SET key. The access code
to access Configuration Menu 1 is
121
.
Use the
,
arrow keys to select the desired configuration option. Use
the
arrow key to toggle between “on” and “off” for that configuration
option or to access a sub-menu for options where a symbolized arrow
“–>” is displayed (see Display 4).
Info
If a menu was accessed but no further action performed, the
menu closes again automatically after approx. 1 minute, and
no change is saved to memory.
If a menu was accessed and closed again, automatically or by
the operator, it can be re-accessed without entering the access
code again for 20 seconds after it was closed.
3.2.1 The Configuration Menu 1
At the level of Configuration Menu 1 (see Display 4b), the following
