Error messages can be displayed via the 4 digital outputs. By means of the error list type
and frequency of the errors can be logged and analysed, also see chapter Programming:

Error Description
Recommended Action
110
Output ½:
Pulse Output
Configuration Error
This error is observed when improperly configuring the full scale
flow, pulse per unit, or pulse width.
This error can indicate the following configuration violations:
1. Pulse frequency exceeds limits at full scale flow
2. Pulse duty cycle is less than 50% at full scale flow
(pulse on time >pulse off time)
Pulse frequency limit is 10 kHz. However, with a non-zero pulse
width configuration, the limit is 500 Hz to achieve a 50% pulse
duty cycle.
If not using the pulse outputs, set the pulses per unit to zero to
allow for reconfiguration of the full scale flow. If it is required to
use the pulse outputs, reevaluate the pulse output configura-
tion. Consider recording and clearing totalizers prior to changing
totalizer units.
120
Display:
Totalizer
Conversion Error –
Totalizer cannot be
properly converted for
display
This error is observed shile trying to change the totalizer units.
Limits of display will prevent improber configuration for the
volume unit dependent on current totalizer values. Consider
recording and cleaning totalizers prior to changing totalizer.
121
Output ½:
Pulse Output
Configuration Error
This error is observed when changing the totalizer untis of
measure. This error implies the pulse configuration exceeds
limits (see error 110). Please note the pulses per unit is not
automatically updated on volume unit reconfiguration. The
pulses per unit should be manually changed to accommodate
the desired units of measure. It may be necessary to set the
pulses per unit to zero then change to the deired totalizer units.
140
Output 3:
Configuration
Error – Full scale
frequency exceeds limits
of relay (1000 Hz)
Reduce full scale frequency setting of output when hardware is
configured for relay operation.
150
Output 3:
Configuration
Error – Full scale
frequency exceeds limits
(10 kHz)
Reduce full scale frequency setting of output when hardware is
configured for open collector operation.
