{LM_d}
Limit – days
{LM_H}
Limit – hours
{LM_M}
Limit – minutes
{LM_S}
Limit – seconds
Ranges of the allowed values of limit items:
{LM_d}
days 0 – 99 as a standard;
{LM_H}
hod. 0 – 23 as a standard (0 – 99 when ignoring the {LM_d} value setting);
{LM_M}
min. 0 – 59 as a standard (0 – 99 when ignoring the {LM_d}, {LM_H} value setting);
{LM_S}
sec. 0 – 59 as a standard (0 – 99 when ignoring the {LM_d}, {LM_H}, {LM_M} value setting).
Note:
Upon entering a non-standard value for any item, all items with a larger time value will be ignored. This allows
to adjust counting to special requirements.
Example after setting DD : HH : MM : SS
5.8.3
Output relay control, switch on time setting {rLPE}
({MEnu}→){Cnt}→{rLPE}
In both modes of the counter it is possible to select the activation of the output relay upon reaching the end of
the set interval - limit. Each NDC clock on which a counter is running, may activate its local relay output.
Through this menu the relay on period upon reaching the counter limit is set {rLPE}
{rLPE}
relay period 0 – 99 sec (0.01 – 0.99 sec; 0.1 – 9.9 sec; 1 – 99 sec)
The on period is set in seconds. The value is entered as a double-digit number, while the position of the decimal
point is set by the ◄/► buttons as necessary a nd confirmed by the OK button.
It is also possible to control a remote output by a counter event. A precondition for that is that the remote output
must be allocated to that clock (see chapter 5.6.6 Allocation of a remote input, address setting {roAd}) and the
clock must be set as a Master. Then the output will be switched on simultaneously with the internal relay.
Note:
1. If the set relay on period is 0 sec, the relay will not be switched on at the selected time!
2. Switching of the relay is signalized by the LED in the right lower corner (after second or minute reading),
that is turned on all the time while relay is switched on.
5.8.4
Counter repeat setting {CrPt}
({MEnu}→){Cnt}→{CrPt}
The {CrPt} parameters specifies how the counter should behave when it reaches the limit. If ON is set, when
the counter reaches the limit, it will startu up again. If OFF is set, when the counter reaches the limit, it will
keep displaying the end value. In the UP mode it will be the set time limit and in the DOWN mode it will be
(00:)00:00.
{CrPt}
counter repeat enabled {On}/{OFF}
Note: If the relay on period {rLPE} > 0 s, the relay will be stitched on for the whole set period, irrespective of
whether the counter started counting again or not ({CrPt} = On).
5.8.5
Enabling of the counter's time correction {Ccor}
({MEnu}→){Cnt}→{Ccor}
If the ON options is chosen, the final period of the counter's counting up/down period will be identical with the
set period irrespective of whether during the counting up/down there is or there is not a change in the setting
of the NDC clock. The time of ending the counting therefore can differ from the expected period of counting. A
change in the time may occur deliberately by resetting the clock by a remote control or automatically by
receiving synchronisation from an NDC net (from the synchronisation module or from the Master clock).
If the the selected option is OFF, the counting up/down period wil be shorter or longer by the difference caused
by a change in the time, it will however, end at the pre-set time.
{CrPt}
Counter correction {On}/{OFF}
5.8.6
Controlling of the counter
The counter may be controlled only when the time counted up/down is currently displayed on the display (e.g.
when altered with other data). Therefore it is recommended not to alter the counter data with other data and
to display them alone.
