Controller overview

 

The pressurisation unit controller is designed to be intuitive to use and allows  

 

 

functions and alarms to be set by the installer/user . It also allows faults to be  

 

 

monitored and logged to enable easier system fault diagnosis .

 

The functions are set using the 4 buttons (A, B, C & D) on the front of the    

 

 

controller and with the help of on screen prompts via the back lit LCD display .  

 

 

On the front of the APU a green ‘power on’ light will be displayed whilst the  

 

 

unit is powered . If an alarm or error is raised the red ‘Error’ light will be  

 

 

 displayed . 

 

A number of pressure set points can be set using the menus, these set points are    

 

detailed below, 1 to 4 and in the description of the function .

 

Button A Scrolls up through menus or increases set values .

 

Button B Enters menus or selects values .

 

Button C Scrolls down through menus or reduces set values .

 

Button D Returns to previous menu

Function list & explanation

 

The functions are contained within an initial display and 3 menus:-

 

Setting menu (pass code protected) see Section 6 .18 .

 

Advanced setting menu (pass code protected) see Section 6 .19 .

 

Test menu (pass code protected) see Section 6 .20 .

Initial display

 

On start up, and during operation, if the APU has had no button inputs for    

 

 

1 minute, a home screen (see Section 7 .11) will be displayed with system    

 

 

pressure, tank water level, any active alarm and any pump that is operating at  

 

 

the time . By using buttons A & C to scroll up or down the following screens will be    

 displayed:-

 

System pressure

 

Active errors

 

System fill status

 

Pump activity

 

Pump run time

 

Alarm reset

Setting menu

 

(Pass code protected, if set)

 

The following functions can be set and modified:-

System pressure (2) 

see Fig . 20

Sets the required system pressure.

 Set in 0 .1 bar increments up 

to the maximum set value for the pressurisation unit model - Midi 130 

& 230 - 3 .5 bar max; Midi 150 & 250 - 4 .1 bar max .

Differential pressure (3)

see Fig . 20

Sets the pressure at which the pressurisation unit will turn 

on at as the system pressure falls.  Relative to the system 

pressure.

 Set in 0 .05 bar increments below the System pressure (2), 

cannot be set above 0 .1 bar below the System pressure (2) .

Hi Alarm (1)

see Fig . 20

Sets high system pressure alarm.

 Set in 0 .05 bar increments 

above the System pressure (2) . Cannot be set below System pressure 

+ 00 .5 bar . Alarm auto resets when system pressure is reduced below 

alarm level .

Lo Alarm (4)

see Fig . 20

Sets low system pressure alarm.

 Set in 0 .05 bar increments 

below the System pressure (2) - Differential pressure (3) - 0 .05 bar . 

Alarm auto resets when system pressure is increased above alarm 

level

System fill

Turns on system fill option

 .  System fill option will turn off once 

the System pressure (2) has been reached or a period of 24 hours has 

passed since it was set to ‘on’ . Lo alarm and Max runtime functions 

are disabled whilst System fill is turned on . Pumps will stop if the 

System pressure (2) or Hi alarm pressure (1) is reached .

Start Activity High

Alarm triggered if the APU starts more than the preset 

limit in 24 Hours.

Set to minimum of 100 starts per 24 hrs . Set in increments of 100 .
