PARAMETERS
GENERAL
(F)
indicates the parameter value factory setting (where applicable)
(V)
indicates the parameter value may be viewed only.
(E)
indicates the parameter value is essential for basic operation.
PARAMETERS
P0
RATE UNITS (E)
Defines the desired Rate display engineering units of measure.
With SW1, contact 5 (SW1-5) in the open position (Imperial units):
enter:
1 = tons per hour (F)(T/h)
1 T/h = 2000 lb/h
2 = long tons per hour(LT/h)
1 LT/h = 2240 lb/h
3 = pounds per hour(lb/h)
4 = pounds per minute(lb/min)
With (SW1-5) in the closed position (Metric units):
enter:
1 = tonnes per hour (F)(t/h)
1 t/h = 1000 kg/h
2 = kilograms per hour(kg/h)
3 = kilograms per minute(kg/min)
The SW1-5 position and the value of P0 should be set before any other programming.
To alter the Rate Units of a programmed CompuScale III, set SW1-5 as desired, perform
a Reset (refer to Parameters/P99 Reset) and set P0 to the desired value.
P1
RATE (E)
Defines the rate of material flow (in P0 units) which will produce the full scale Rate output. (F=0.0000)
enter:
Design Rate from Design Data Sheet, Range = 0.0001 to 99999
P2
LOCAL TOTAL (E)
Defines the amount of material to be totalized, prior to initiating an internal totalizer (and Main / Sub Total
display) update, (F = 1). The weight portion of the Rate Unit (P0) is assumed.

If [TOTAL REGISTRATION TOO LOW] is displayed, enter a higher value.
P3
REMOTE TOTAL
Defines the amount of material to be totalized, prior to initiating a remote totalizer relay contact closure, (F = 1).
The weight portion of the Rate Unit (P0) is assumed.
The frequency of remote totalizer contact closures is dependent upon the material flowrate and the Remote
Total value. When a remote totalizer is connected to TB1-48,49, refer to the totalizer manufacturers instructions
to determine the maximum pulse frequency. Lower values increase and higher values decrease the relay
contact closure frequency.
