4. PROGRAM PARAMETERS
4.1 PIN No. Program Protection
The option exists to protect the programmed detail & Accum. Total with a user selected four
digit PIN No. ( 0000 represents no PIN protection ). If activated the user must input the correct
PIN No., failure to do so will deny access to change any of the program parameters or reset
the Accumulative Total but will allow the user to step through and view the program details.
Only one PIN number may be set but this can be changed at any time after gaining access
through PIN entry. A second back up PIN number is installed at the factory should the
programmed PIN be lost or forgotten. ( refer page 14 for the back up PIN No. )
4.2 Resetting Accumulated Total
Resetting the accumulated total can only be done within the program mode.
4.3 Engineering Units ( refer clause 1.4 )
Select from available Eng. units to right of the display. The BT can display in engineering units
not available on the LCD display by programming to “no eng. units” and a suitable K-factor.
4.4 K-factor (scale factor)
Enter K-factor starting with the most significant number, up to 8 prime numbers & 3 decimal
numbers can be entered. Trailing decimal numbers move into view as digits to the rig ht are
progressively selected, any significant digits which may move from view remain functional.
4.5 Pulse output
The pulse output is NPN-PNP link selectable via jumper J1. It is also selected at jumper J3 to
act as a non-scaled pre-amplified pulse output or scaleable pulse output, maximum load is
50mA.
Non-scaled pulse output:
The un-scaled repeater pulse output represents one pulse out for each input pulse from the
primary measuring element (flowmeter). This output acts as an input signal pre-amplifier
particularly suitable for pick-up coil inputs up to 5Khz. The duty cycle of the output adopts the
duty cycle of the input. The instrument needs to be externally powered for this feature to
operate (see page 11).
Scaleable pulse output :
The fully scaleable pulse output is programmable as the number of litres / gallons etc. per
output pulse Eg. 0.1 litres/pulse, 10 litres/pulse, 100 gallons/pulse. Range is 0.1 ~ 9999.9
Eng. unit/pulse. The instrument needs to be externally powered for this feature to operate
( p11 ).
The scaleable pulse output is suitable only for remote integration due to the spasmodic nature
of its output frequency, it is limited to 8hz. Should the potential incidence of this output exceed
8hz it can continue to count after flow has stopped until such time as the processor buffer has
completed integration. Most scaleable pulse output requirements are low frequency due to
down scaling and therefore not effected by the buffer count effect.
