User manual for - TIMER SLC-94
Parameter “
” has no any effect in the formats : „
h-m
”, „
h-h10
”.
Signal {
RESET
} clears only main timer, totalizer value stay not changed. Control
signals {
START
} & {
STOP
} control triggering and stopping of both counters (main
timer and totalizer) simultaneously
After value 99999.9 hours is exceeded the device displays message “
ovEr
” in place of
value, but counting is not stopped, and its current value can be read via RS-485 interface.
Enabling / disabling and clearing of the counting can be done via galvanic isolated inputs
(according to settings), using local keyboard (if option “
PuSH
” has been set to “
on
”) or via
RS-485 interface.
Starting, stopping, and clearing of the counter via serial interface is affected by
delay errors, depends on transmission speed and parameter
„rESP”
. Example
minimum delay while
„Baud”
=
9.600
and
“rESP”
= S
td
equals about 14ms. The
delay can be calculated using formula:
t

The functions of keyboard while normal operation:
START of counting (while ”
PuSH
” is active). Button inactive if parameter
“
StArt
” has been set to “
Lo
” or “
Hi
”.
STOP of counting (while ”
PuSH
” is active).Button inactive if parameter
“
StArt
” has been set to “
Lo
” or “
Hi
”.
Manual clearing of currently displayed counter - timer or totalizer, requires
of acknowledgement by
[ENTER]
button.
switches display between main timer and totalizer values
Enter to menu programming mode (press and hold at least 2 seconds).
•
The counting is independent of operation mode. After entering menu mode
device keep counting, it is made in background;
•
In case of power fail, after next power-on device is stopped. Main timer and
totalizer shows their values stored while power-off. Proper configuration of the
inputs allows counting directly after power on.
