Foster Refrigerator FHG 2L User Manual

Display Case  
FHG 2L & FHG 3L  
 
Introduction  
The display case are manufactured in two formats FHG 2L, 2 doors, and the FHG 3L, three doors.  
There are also Multiplex options that are a combination of two FHG 2L cases to make a FHG 4L or a combination  
of the FHG 2L and FHG 3L to make a FHG 5L.

Controller Display and Symbols.  
NOTE: When the buttons are pressed a brief audible signal is emitted; this signal can not be disabled.  
1.  
2.  
3.  
HACCP: Pressing this button displays a sub menu used to access the HACCP parameters (not used by  
Foster)  
ON/OFF: When pressed for more than 5 seconds switches the controller on/off. When OFF the controller  
display alternates between “OFF” and the air temperature as read by the air probe.  
PRG/MUTE:  
Mutes the audible alarm and deactivates the alarm relay.  
: If pressed for more than 1 second the during the reception of the automatic network address  
assignment request package, starts the address assignment procedure (not used by Foster).  
: If pressed for more than 5 seconds, allows access to the menu for setting the “F” (frequent)  
parameters.  
: If pressed for more than 5 seconds together with,  
allows access for setting the “C”  
(configuration) Parameters.  
: If pressed for more than 5 seconds when switching the instrument ON, activates the procedure for  
setting the default parameter values.  
: If pressed for more 5 seconds together with,  
resets any active alarm with manual reset (the message  
‘rES ‘ indicates that the alarm has been reset); any delays relating to the alarms are re-activated.  
4.  
UP/CC: If pressed for more than 5 seconds, activates/deactivates the continuous cycle operation (the  
message ‘ccE’ and ‘ccE’ indicate, respectively, the start and end of the continuous cycle request).

Programming the controller.  
The parameters can be modified using the front keypad.  
The operating parameters are divided into two families: Frequent parameters (type “F”) and configuration  
parameters (type “C”).  
Access to the configuration parameters is protected by a password that prevents unwanted modification or access  
by unauthorised persons.  
Accessing the type “F” parameters.

Parameter Definitions  
/2  
/3  
/4  
Measurement stability.  
Defines the coefficient used to stabilise the temperature reading.  
Probe display rate  
Sets the rate at which the temperature display is updated.  
Probe average (Virtual probe)  
Used to choose whether to control the temperature based solely on the room probe reading, or  
alternatively whether to refer to the average of the room probe S1 and probe 2(S2, see parameter /A2).  
/5  
/6  
Select °C or °F  
Defines the unit of measure in degrees centigrade or Fahrenheit.  
Decimal point  
Used to enable or disable the displaying of the temperature with the resolution to the tenth of a degree  
between –20 and +20.  
/tI  
Probe displayed by instrument  
Select the probe to be displayed by the instrument.  
Warning: Control is always based on the virtual control probe.  
/tE  
/P  
Probe displayed on external terminal  
Selects the probe to be displayed on the remote terminal.  
Select type of probe  
Used to select the type of probe for temperature measurement.  
Default. /P = standard NTC probe with range –50 to +90°C.  
/A2  
/A3  
/A4  
Configuration of probe 2  
Used to configure the operating mode of probe 2.  
Default: /A2 =2 = Defrost probe.  
Configuration of probe 3  
Used to configure the operating mode of probe 3.  
Default: /A3 = 0 = Probe 3 absent.  
Configuration of probe 43
