18) Speed Spn - Speed Spn is used to calibrate the belt SPEED if the WP20 displayed
SPEED does not equal the tested or calculated belt SPEED. Increase Speed Spn to increase the
SPEED value or decrease it to decrease the SPEED value.
19) mA Damp - Enter the damping factor for the RATE current loop output if used. The
damping factor smoothes the current signal. Like RATE and SPEED damping, current loop
damping does not affect system accuracy. With high damping, however, the RATE current loop
output signal will lag behind the actual RATE. A typical value for mA Damp is 30.
20) Base mA - Enter the RATE current loop output value desired when the RATE equals
zero. Remote auxiliary devices such as a chart recorder or display will typically use 4 mA to
represent zero RATE. The default value is 4 ma.
21) Rate 20mA - This Parameter sets the RATE that corresponds to a current output of 20
mA . This RATE should be a minimum of 10% higher than the maximum RATE expected. If the
actual RATE were to exceed this Parameter’s value, the current output will remain at 20 mA. For
example, if the maximum RATE is 200 tons/hr, enter 220 for this Parameter.
22) Rate LTrm: - This Parameter allows fine tuning of the Base mA output Parameter. A
milliamp range ammeter will need to be connected to the output terminals for this adjustment.
Increase the number to increase the current and decrease the number to decrease the current.
23) Rate HTrm: - This Parameter allows fine tuning of the Rate 20mA Parameter. A
milliamp range ammeter will need to be connected to the output terminals for this adjustment.
Increase the number to increase the current and decrease the number to decrease the current.
24) HFR Damp - Enter the damping factor for the H igh F requency R ate (HFR) output if
used. The damping factor smoothes the HFR signal, but does not affect accuracy. With high
damping, however, the HFR signal will lag behind the actual RATE. It is typical to set the HFR
Damp setting the same as the Rate Damp setting (Section 6.02.24).
25) Total DP - Enter the desired decimal point position for the TOTAL window. Higher
RATES make decimal positioning unnecessary, because the TOTAL will increment at one or
more units at a time. The decimal point positioning for various positions will appear as:
Ones 00000000
Tens 000000.0
Hunds 00000.00
Thous 0000.000
If the TOTAL exceeds the display size, a series of dashes will appear in the TOTAL window and
will look like -------- .
26) Down
Count - This Parameter enables or disables down counting of the TOTAL display.
When set to Down Count: NO, the totalizer will not count down (backwards) when the RATE
display is indicating negative. When set to NO, the AZT Parameter must be set to 0000 for
proper operation.
NO disables down counting.
YES enables down counting.
