Q21924 end of daylight saving 9918 0
Selects the time of the year when daylight saving will end.
Q21925 daylight saving time (DST) 9920 0
Shows if daylight saving is on or off. If automatic daylight saving correction is off, then this setting may
be used to move the clock forwards or backwards by one hour.

Digital inputs
The following settings select the function of the digital inputs. The hint line shows (off) when there is
no voltage present, and (on) when voltage is applied to the input.
The UP and DOWN keys can be used to select the function from the available list.
The list is shown in the Instruction Manual in the ‘I/O Function Table’.
Q2211 IN1 function
(& state)
6
8170, g3
7
no function=0
Q2212 IN2 function (& state) 8172, g3 enable flowrate=13
Q2213 IN3 function (& state) 8174, g3 run=2
Q2214 IN4 function (& state) 8176, g3 reset total=32
Q2215 IN5 function (& state) 8178, g3 print=40
Q2216 IN6 function (& state) 8180, g3 print total=41
Q2217 IN7 function (& state) 8182, g3 stop=1
Q2218 IN8 function (& state) 8184, g3 pause=3
Q2219 IN9 function (& state) 8186, g3 enable flowrate=13
Q2210 IN0 function (& state) 8190, g3 pulse input=0
Tacho input
A tacho can be connected to the pulse input to measure the rotational speed of a shaft.
Q2229 speed 8708, g4 rpm
This is the rotational speed measured on the tacho input.
Loadcell input (impact weight)
Input settings
Q22311 AI1 response time [0.04 to 32] 8120, g1 2.00 s
The response time for the weight signal. A larger value will help reduce variations in the weight reading
caused by vibrations or movement on the weighing system.
Q22312 lever ratio 8130, g1 1.0000
The lever ratio adjusts the weight reading during calibration. It is the ratio of calibration weight (test
weight) to displayed weight (gross weight).
5
Defaults to whatever the current setting is.
6
Hint line shows state as (on) or (off)
7
See I/O Function Table page 46. Use negative numbers to reverse the signal sense eg 1=stop (stop when input is on), -1=NOT stop
(stop when input is off).
