User manual - COUNTER SLE-73
Due to problem with direct displaying of “ m ” letter, it is exchanged with special sign
“ “. Independently in user manual letter „ m ” is used to make it more readable
(example: “modE” ).
7.3.1. “rESEt” parameter
This parameter determines the counter zeroing (reset) sources, and can be set to one of
the values:
”ALL” - this option enables both manual (using [RESET ] button) and electronic reset.
”EL”
- this option enables external programmable input. If an active signal is delivered to
this input the counter is zeroed (only if “
Pr inP
” = ”
rESEt
”), and the result stays zero
(or equal to offset) as long as the signal on programmable input is active. To made
correct zeroing, input signal must be active at least by 1 ms. In this mode manual
reset is disabled.
”mAn” - manual reset only. This value enables only manual reset, which can be done by
pressing the [
RESET ] button on the front panel. This operation must to be approved
by [
ENTER
] button. After zeroing counter displays value equals to
”oFFSEt”
parameter. In this mode electronic reset is disabled.
”nonE”
- this option disables both manual and electronic reset.
Zeroing of the counter can be done via RS-485 interface (by presets of some
registers with value 0000h) independently of the
„rESEt” parameter value. After
zeroing the counter, displayed value is equal to „ oFFSEt” parameter. Remote
zeroing is available in all modes (
”ALL”
,
“EL”
,
“mAn”
,
„nonE”
).
7.3.2. “FiLtEr” parameter
This parameter enables the digital filter, which filters the contacts oscillations of switches
(mechanical detectors). Digital filter eliminates the counting errors when mechanical detectors
are used. This parameter can be set to values:
”OFF” , ”10” ÷ ”90”, where its value express
the maximum passed frequency, if ”OFF” is set the filter is disabled (see DIGITAL FILTER ,
page 13).
7.3.3. “Pr inP” parameter
This parameter defines the function of the programmable input. When
active state
is
delivered to programmable input, it causes of the activating of particular function. This
parameter can be set to one of the values:
”diSAbL” - programmable input is not active,
”rESEt” - zeroing of the counter value (the active state must be longer than 1 ms).
”inhibi”
- programmable input stops the counting,
”dirEct” - active signal on the programmable input changes counting direction
