Two security code levels, 1 and 2, are available, and are
each accessed with a five digit number.
User Code Level 1 default number is 10760.
Engineer Code Level 2 default number is 56360.
Parameters accessible by the two levels are shown
above.
At the flashing cursor on the first digit of the Login code
number, press either or membrane switches to
reach the required digit.
Tosetthis digit and pass to the nextdigit,depress the
switch. Continue until all digits have been set, and
depress the switch to enter the complete code.
If an incorrect value is entered, access to subsequent
programming pages is prevented and the display reverts
to the Operating Page.

PARAMETER DESCRIPTION
Alarm No1 Idle Idle state for alarm output.
With no alarm active:
0 = Low (O/P transistor ON)
1 = High (O/P transistor OFF)
Alm No1 En 0 = Alarm output disabled (set to
idle state).
1 = Alarm output enabled.
Alm No1 Fault Alarm occurs for System fault.
Alm No1 Fwd Alarm occurs for forward flow.
Alm No1 Rev Alarm occurs for reverse flow.
Alm No1 Cutoff Alarm occurs for Pulse Output
Cutoff.
Alm No1 Mtsnsr Alarm occurs for empty sensor.
Alm No1 Hi Alarmoccurs forFlow ≥‘AlmTripHi’.
Alm No1 Lo Alarm occurs for Flow ≤‘Alm Trip Lo’.
Alm No1 Anlg Alarm occurs for Analogue Output
over range.
Alm No1 Pls Alarmoccursfor Pulse Output over
range.
PARAMETER DESCRIPTION
Tot Unit Select totaliser measurement units.
Tot Mult Select multiplier units required.
Tot ClrEn Enter '1' to enable totaliser reset
function to be used from front panel.
PARAMETER DESCRIPTION
Inpt Set up external logic input function:
'Zero' sets flowrate output to zero.
'Hld' holds flowmeter output value.
'Clr' resets all totalizers.
'Anlg' selects Anlg No2 Range.
Inpt Idle Enterinactivestate of input contact:
'1' for Hi normal
'0' for Lo normal. SECURITY PASSWORD
Login Key 1 Set Level 1 security password.
Login Key 2 Set Level 2 security password.
#The maximum which can be entered must not exceed
21000. The value entered may be displayed with a small
error in the decimal digits e.g. 1.900 may be displayed as
1.899. This is a display characteristic and the value 1.900
will be used by the MagMaster.
§Select both parameters for bidirectional operation (e.g.
when dual current output is fitted). If both are zero, then IOUT
is always 0%.
‡On performing a Rapid Reset/Escape to return to
'Operation' level, 'Test Mode' is automatically cancelled.
ØIf the sensor is empty or disconnected, the alarms
'MtSnsr' and 'Coil' will be displayed as appropriate.
PARAMETER CHANGES FLOW MEASUREMENT
When a parameter is selected, which holds one or more
variable units e.g. 'Flow Unit' parameter which can be
Liters, Cubic meters, Gallons etc., proceed as follows to
change the units: ('Flow Rng' selected).
'Flow Unit' selected
Press or switch to change the units.
✶
Note. The existing units will flash at the first
depression of the or switch, and further
switch depressions will change the type of units
displayed.
Depressing the switch will now enter the newly
selected units.
This type of action is similar for all variable units.
Where numerical values are to be changed, initial
depression of the or switches cause the first of
five digits to be highlighted by a flashing cursor. Change
the value with the and switches, the particular
digit with the switch, and enter the final selection with
the switch.
The correct security level MUST be selected – see
SECURITY ACCESS.
Select the parameter to read the value, or to change it as
necessary. All ‘live’ data displayed is updated each
second.
Use the key to move between pages.
Use the key to move between parameters.
The and keys change displayed values and units.
The key will accept the chosen value or unit.
