The first 7 values (1234MLS) each represent a single digital input. A ‘1’ indicates that that input is
ON, and a ‘0’ indicates that the corresponding input is OFF. "1234" represents the four physical digital
inputs, DI1 to DI4. "M" is the mains fail status (‘1’ for mains fail, ‘0’ for mains OK). "L" is the battery
low volts status (‘1’ for low volts ‘0’ for OK). "S" is the set-point status.
P CNT, AI1, AI2, P RATE, and VBATT each represent 16 bit values, displayed as four hexadecimal
digits.
P CNT is the current value of the pulsed input counter. This value should increment each time ‘DI 1’
turns from OFF to ON. P RATE displays the current pulse rate at DI1. This value is scaled according
to the MAXRATE value configured (0 Hertz is displayed as 4000, and the maximum rate is displayed
as C000).
AI1 and AI2 represent the value for the two analog inputs. Full scale input (20 mA) is displayed as
C000, 4mA is displayed as 4000, and 0ma is displayed as 2000. Analog inputs are filtered digitally
with a time constant of 1 second, so a sudden change in the analog input current will result in a slower
change in displayed analog value, finally settling at the new value.
A guide to translate the displayed value to the analog input current is provided below.
Add together the figures corresponding to each digit in each position to
determine the current (mA)
e.g. displayed value 3456 = 2.000+0.500+0.039+0.003
= 2.542mA
