Use Of The Unit (Menu Structure); Test Mode (Menu Option 1, Level 1) - Pfannenberg Multi-Controller Manual De Instrucciones De Servicio

During normal running
Current switch cabinet internal temperature TS1 (if two tempe-
rature sensors TS1 and TS2 are used these are displayed alter-
nately for 15 sec). The position at bottom right indicates whether
in °C or °F
When a system fault occurs
The highest value error number alternates with the temperature
from TS1 (switch cabinet internal temperature) or TS2
In menu mode
Display of the selected menu option or the current parameter
and information values
The temperature range of TS1 and TS2 in the display is from 0ºC to
+90ºC (+32ºF to +194ºF). If the temperature is below 0ºC (+32ºF) a
'u' appears in the display. At temperatures above +90ºC (+194ºF)
an 'o' appears in the display.

3. Use of the unit (menu structure)

Attention!
Default factory parameters may only be modified by
authorised individuals.
The menu is activated by pressing the 'MODE' button for at least 4
seconds while in operational display mode (normal operation) (see
also Figure 2). In this mode the unit stops all motors. The status of
the error message output remains unaltered in this case.
The menu consists of 3 levels, each of which contains a different
number of menu options. If no entry has been made for 60 seconds,
regardless of menu option, the unit changes automatically to
operational display, and normal operation is restarted.

3.1. Test mode (menu option 1, level 1)

Using this function, a function test of the unit can be carried out
regardless of the ambient conditions. Before executing the function
test, the coded number of the connected temperature sensors
recognised by the system is displayed for 30 sec. The number of
temperature sensors is coded as per Table 1.
This test is also carried out every time the cooling unit is connected
to the mains supply.

*Control sensor: This temperature sensor is used to control
the switch cabinet internal temperature
Analytical sensor: This sensor can be used for analytical pur
poses (e.g. temperature monitoring of spe
cific switch cabinet components and deter
mination of 'hot spots'), and can be sited by
the user as required.

After the test mode has elapsed (30 sec.) the unit changes
automatically into normal mode. If errors occurred during the test
run, these are displayed alternately with the temperature.
3.2. Setpoints (menu option 2, level 1)
This menu option includes all parameters which affect the cooling
operation of the unit. The setting of the temperature setpoint T
