Digital set value for PID
The digital set value is used for the PID mode if there is no analog input active. The analog input
applicable for this feature is milliamps in (pin 5/6).
USED IN:
PID mode.
RELATED VARIABLES:
Active set value/mA’ in and mA scaler/mA’s.
HEX ADDRESS:
00B4 HEX ‐‐‐‐> same address used in EMO‐2000
BYTES:
4 Bytes DEFAULT: 360 cc/m
ASC form COMMAND:
reading = 103; writing = 503; E is engineering units; E is in selected
engineering units. N is normalized units in cc/m.
Sample amount for Rate A
The sample amount has an effect on the “mellow” rate number. The sample amount is used in a digital
filter formula to calculate the actual rate. The bigger the sample amount the more sluggish the rate
reacts. The formula for the filter is:
RATE MELLOW = (OLD RATE MELLOW x SAMPLE AMOUNT+NEW RATE)/(SAMPLE+1)
USED IN:
All modes.
RELATED VARIABLES:
Rate A mellow.
HEX ADDRESS:
0087 HEX ‐‐‐‐> same address used in EMO‐2000.
BYTES:
2 Bytes DEFAULT: 2
ASC form COMMAND:
reading = 104; writing = 504; E and N return same number.
K‐Factor for Rate A KFR (including the decimal point)
The KFR is a factor that scales the display to the incoming frequency on channel A, which is on pin 4. You
can enter the decimal point in ASC‐form communication. If you use the OPTO type communication, then
you must enter the decimal point separately.
The formula for calculating the KFR value is:
