ProtEX-MAX PD8-6210 Explosion-Proof Analog Input Batch Controller
Instruction Manual

Error Message (
Error
)
An error message indicates that the calibration or scaling
process was not successful.
After the error message is displayed, the controller
reverts to input 2 during calibration or scaling and to
input 1 during internal calibration, allowing the
appropriate input signal to be applied or programmed.
The error message might be caused by any of the
following conditions:
1. Input signal is not connected to the proper
terminals, or it is connected backwards.
2. Wrong signal selection in
Setup
menu.
3. Minimum input span requirements not
maintained.
4. Input 1 signal inadvertently applied to calibrate
input 2.
Minimum Input Span
The minimum input span is the minimum difference
between input 1 and 2 signals required to complete
the calibration or scaling of the controller.

Time Base, Total Conversion Factor
& Total Reset
The time base, total conversion factor, and total reset
menus are located in the
Program
menu.
The total and grand total have their own independent
settings. This means that one can be displaying the
value in gallons while the other displays in million
gallons, liters, m
3
, etc.
Time Base
The time base is the amount of time over which the
rate parameter should accrue. For example, if the rate
was ten and the time base was in minutes, then the
total would increase by ten every one minute.
Total & Grand Total Conversion
Factor
The total & grand total conversion factor is the
amount by which the rate is multiplied before it is
added to the total or grand total.
For Example, if the rate was 10,000 gallons per
minute and the total conversion factor was 0.001, the
total would increase by 10 every minute. This is
useful, for instance, if you want to show rate in gallons
and total in thousands of gallons.
