(POS. 6.1-6.2-6.3-6.4) Function corresponding to on/off outputs 1-2-3-4
To choose the function associated to digital Output 1. The functions are listed in the table below.
The outputs 3-4 are optional, furthermore output 4 is the only output, which can reach a
12.5 KHz frequency.
OFF: DISABLED
#1 IMP+: PULSE ON CHANNEL 1 FOR POSITIVE FLOW RATE
#1 IMP-: PULSE ON CHANNEL 1 FOR NEGATIVE FLOW RATE
#1 IMP±: PULSE ON CHANNEL 1 FOR POSITIVE AND NEGATIVE FLOW RATE
#2 IMP+: PULSE ON CHANNEL 2 FOR POSITIVE FLOW RATE
#2 IMP-: PULSE ON CHANNEL 2 FOR NEGATIVE FLOW RATE
#2 IMP±: PULSE ON CHANNEL 2 FOR POSITIVE AND NEGATIVE FLOW RATE
#1 FREQ+: FREQUENCY CHANNEL 1 FOR POSITIVE FLOW RATE
#1 FREQ-: FREQUENCY CHANNEL 1 FOR NEGATIVE FLOW RATE
#1 FREQ±: FREQUENCY CHANNEL 1 FOR POSITIVE AND NEGATIVE FLOW RATE
#2 FREQ+: FREQUENCY CHANNEL 2 FOR POSITIVE FLOW RATE
#2 FREQ-: FREQUENCY CHANNEL 2 FOR NEGATIVE FLOW RATE
#2 FREQ±: FREQUENCY CHANNEL 2 FOR POSITIVE AND NEGATIVE FLOW RATE
SIGN: FLOW DIRECTION OUTPUT (ENERGISED = -)
RANGE: RANGE INDICATION OUTPUT (ENERGISED = SCALE 2)
MAX AL+: MAX DIRECT FLOW RATE OUTPUT(ENERGISED = AL. OFF)
MAX AL-: MAX REVERSE FLOW RATE OUTPUT(ENERGISED = AL. OFF)
MAX AL±: MAX DIRECT/REVERSE FLOW RATE OUTPUT(ENERGISED = AL. OFF)
MIN AL+: MIN DIRECT FLOW RATE OUTPUT(ENERGISED = AL. OFF)
MIN AL-: MIN REVERSE FLOW RATE OUTPUT(ENERGISED = AL. OFF)
MIN AL±: MIN DIRECT/REVERSE FLOW RATE OUTPUT(ENERGISED = AL. OFF)
MAX+MIN±: MAX AND MIN FLOW RATE ALARM OUTPUT (ENERGISED = AL. OFF)
EMPTY PIPE: EMPTY PIPE ALARM OUTPUT (ENERGISED = FULL PIPE)
OVERFLOW.: OUT OF RANGE ALARM OUTPUT (ENERGISED = FLOW RATE OK)
HW ALARM: CUMULATIVE ALARM OUTPUT interrupt coils, empty pipe, measure error (ENERGISED = NO
ALARMS
BATCH AL: BATCH ALARM
EXT. COMM.: ONLY AVAILABLE WITH DATA LOGGER MODULE
BATCH SIN.: AT THE AND OF BATCH THE OUTPUT CHANGE STATUS
END BATCH.: END BATCH OUTPUT (ENERGISED =BATCH IN PROGRESS)
PREBATCH.: PREBATCH OUTPUT (ENERGISED = PREBATCH IN PROGRESS)
(POS. 6.5) Duty cycle value for pulses/frequency output
The duty cycle function defines the time ratio between ON and OFF states when frequency outputs are
used: 50% means that ON phase will be as long as OFF phase, 60% means that phase ON will last
60 % and phase OFF 40% of the total time cycle.
When pulse outputs are used, the duty cycle only defines the OFF phase because the ON phase is
already set with the function "PULSE DURATION" (see menu "SCALE"). In this case if, for example,
the duty cycle is set to at 50% and the pulse duration to 50ms, OFF phase will be the same as ON
phase. The formula to calculate the minimum time of the OFF phase and the time of total cycle is the
following:
T. total cycle= 100 x (pulse duration in ms)/ (duty cycle)
T. OFF phase = T. total cycle - pulse duration
