4-12 OPERATION CHAPTER 4
Display series DN-107P
4.3.6. Function 4. Chronometer
The chronometer function permits working with the display as a stopwatch. It can be
programmed to increase, decrease or increase/decrease depending on an input.
Besides of the control inputs that resets the display or loads a preset (it has two presets)
, it’s
also possible to reset de display, load a preset or stop it automatically with the alarms
Programming the automatic functions:
The automatic functions are
programmed modifying the right’s digit of the second parameter
02.Co. (See Error! No s'ha trobat l'origen de la referència.
“Error! No s'ha trobat l'origen de
la referència.
”).
When the chronometer’s value is equal to one of the values of the alarms, one programmed
action starts.
Example:
Parameter 2 Co = 35.
Parameter 4 P2 = 15 - 30.
Parameter 5 A1 = 30 - 28.
The parameter 2 has programmed increase minutes and seconds. Load the preset 2 (15m -
30s) when the chronometer is equal to the alarm 1 value (30m - 28s)
Displays with relay:
If the display has the relay option, the relay can be configured to be activated in different
situations. Each relay has an independent parameter to program. (see 4.3.2)
Example:
Parameter 7 S1 = 58
Activate output 1 if the chronometer’s value is bigger than the alarm 1, the output is flashing, 1
second is On and 1 second is Off.
Combining the automatic functions (parameter 2) with the output functions (parameters 7 and
8), the display can have many applications.
Control inputs:
The power supply of the inputs should be between 12V and 26V CC and the inputs can
be PNP, NPN or CONTACT.
E1 Control Run = ON / Stop = OFF.
E2 Reset
E3 Loads preset 1
E4 Loads preset 2
E5 Increase = ON / Decrease = OFF.
