Examples:
a) Configuration of pulse output [R, S] for mass:
o
Select value 1 for parameter ID [R/S01]
o
Acc. to Table 10, the parameter [R/S02] has to be selected. This parameter specifies
the mass equivalent to one pulse. E.g. when set to 0.001kg, a mass transfer of 1kg
will cause 1000 pulses
b) Configuration of a frequency output [R, S] for mass flow rate:
o
Select value 13 for parameter [R/S01]
o
Acc. to Table 10 the parameters [R/S04 & 07] have to be selected. The parameter
[R/S04] specifies the mass flow rate equivalent to the frequency set under
parameter [R/S07]. E.g. when [R/S04] is set to 1kg/min and [R/S07] is set to 1000Hz
a mass flow rate of 5kg/min will cause a frequency of 5000Hz
c) Configuration of a digital output [I-L] for mass flow alarm:
o
Select value 1 for parameter [I-L01]
o
Acc. to Table 10 the parameters [I-L02, 03 & 04] apply. Select the needed alarm type
[I-L02] and enter the low [I-L03] and high [I-L04] alarm values. The unit of the alarm
is determined by the digital output configuration [I-L01]. For mass flow alarm the
unit is fixed to kg/min

Versatile Digital Output Configuration:
Used to assign different functions to the pulse output.
In simple pulse mode, Pulse1 and Pulse2 operate independently. In phase shift
mode, Pulse1 and Pulse2 work together to produce the desired pulse output
relationship. In phase shift mode, both outputs (Pulse1 & Pulse2) should be set to
the same mode.
0: Pulse output is off.
