27) RLY 1 Func - Relay 1 can perform four different functions. Select the function desired.
TPR - Total Pulse Repeater, relay 1 is activated in increments of the TOTAL.
HLRA - High/Low Rate Alarm, relay 1 is activated when the RATE is outside a specified
range.
HLSA - High/Low Speed Alarm, relay 1 is activated when the SPEED is outside a
specified range.
SPAN - Auto Span output, relay 1 is activated during an Auto Span to lower or raise the
calibration weight(s).
Note: the following six relay Parameters only appear when its above associated relay function is
selected. All use the RLY 1 Lgc Parameter.
TPR uses RLY 1 Pls and TS.
HLRA and HLSA use RLY 1 Low, High, and Delay.
HLRA also uses RLY 1 Set pnt.
SPAN does not use any other Parameter.
28) RLY 1 Lgc – The relay’s “normal” state can either be de-energized (N.O.) or energized
(N.C.) state.
N.O. – Normally open or de-energized state.
N.C. – Normally closed or energized state.
29) RLY 1 Pls - When TPR is selected, enter the duration of the relay pulse, in seconds, that
drives the remote totalizer. The relay must be closed for at least 0.10 seconds, but the option
exists for keeping it closed longer, as long as that does not conflict with the following RLY 1 TS
Parameter (the relay cannot be closed longer than the time between pulses, because that would be
the equivalent of a continuous on). Start with 0.10 seconds and increase the value if the remote
totalizer does not respond to the shorter pulse.
30) RLY 1 TS - When TPR is selected, enter the frequency of the relay pulse or the "total
scaling". For example, set RLY 1 TS to 1.00 to close the relay every 1 ton. Set to .01 to close the
relay every .01 tons. If RLY 1 TS is set too small and the RATE is too high, there will not be
enough time to open and close the relay. It is best to set it so the relay closes once every few
seconds.
31) RLY 1 Low - When HLRA is selected, enter the lowest RATE allowed before the low
RATE alarm relay is activated. When HLSA is selected, enter the lowest SPEED allowed before
the low SPEED alarm relay is activated.
32) RLY 1 High - When HLRA is selected, enter the highest RATE allowed before the high
RATE alarm relay is activated. When HLSA is selected, enter the highest SPEED allowed before
the high SPEED alarm relay is activated.
33) RLY 1 Delay – When HLRA or HLSA are selected, enter the time delay, in seconds, that
a high or low RATE or SPEED alarm condition can exist before the alarm relay activates. For
example, setting the delay to 10 seconds will allow the rate to fall below RLY 1 Low for 10
seconds before the alarm is activated. The delay eliminates false or nuisance alarms when the
RATE or SPEED momentarily go outside the preset boundaries.
34) RLY 2 Func - Relay 2 can perform four different functions. Select the function desired.
TPR - Total Pulse Repeater, relay 2 is activated in increments of the TOTAL.
