User Manual For - CONTROLLER/DATA RECORDER MultiCon CMC-99/141
the input signal. The device stops counting time when it detects another falling
edge on this input.
–
Reset now
– the button which allows the user to reset the counter manually,
–
Reset mode
– it allows to choose resets for the counter, it has the following
parameters:
•
disable
– no additional resets,
•
from log. channel
– an additional reset is the logical channel selected from
the list in the
Reset source
parameter, it is activated by a high state,
•
external
– an additional reset can be the counter’s programmable input, but
the
Prog. Inp. mode
parameter has to be set as
reset
in order to work properly,
•
both
– both options shown above are active, but the
Prog. Inp. mode
parameter has to be set as
reset
in order to work properly,
–
Reset source
– this parameter is visible when the
Reset mode
is set as
from log. channel
or
both
, it contains a list of logical channels and the chosen one
will reset the counter when its value is higher than
0
,
–
Prog. inp. mode
- specifies the counter reaction to higher than
0
value appearance
on the
PRG
input; it has the following parameters:
•
binary input
– signals on the programmable input are not affecting the counter's
work, but they are measured and can be used and displayed by setting
the source for logical channels as one of five (for HM4) or three (for HM2) last
inputs which the module offers; for more details see below in this chapter,
•
reset
– allows to reset the hourmeter asynchronously, but the
Reset mode
parameter has to be set as
external
or
both
in order to work properly,
•
inhibit
– allows to inhibit time counting temporarily,
–
Prog. inp. trig.
- allows to define when the device should reset or inhibit
the hourmeter (depending on the
Prog. inp. mode
parameter settings),
•
high level
– the device keeps the counter in the reset or inhibit state during
a high state on the programmable input,
•
low level
– the device keeps the counter in the reset or inhibit state during a low
state on the programmable input,
•
rising edge
– the device resets the counter asynchronously when the rising
edge occurs and the
Prog. inp. mode
parameter is set as reset, or inhibits the
counter when the rising edge occurs and the
Prog. inp. mode
parameter is set
as inhibit, but in this case the counter will start counting again when a new
trigger occurs on the
Start/Stop
input,
•
falling edge
– the device resets the counter asynchronously when the falling
edge occurs and the
Prog. inp. mode
parameter is set as reset, or inhibits the
counter when the falling edge occurs and the
Prog. inp. mode
parameter is set
as inhibit, but in this case the counter will start counting again when a new
trigger occurs on the
Start/Stop
input,
–
Filter
– sets the filter on counter inputs which allows to get rid of negative effects of
signal bounces; it has the following parameters:
•
disable
– the filter is inactive, recommended only in the situation when the
electronic input of another device is connected to the counter input,
•
10 ÷ 90
– the filter is active; setting one of the frequencies causes the fact that
input signals whose duration corresponds to half of the selected frequency will
be considered as unwanted signal bounces and ignored. Using this option is
recommended when the contact output of another device is connected to the
counter input,
