General description of multifunctional counter General description of multifunctional counter When the application input is used as an additional count input, the above mentioned input frequencies have to be reduced by the frequency of the ap plication input: Application input/output: Depending on the standard function, up to 11 (eleven) functions can be assig ned to the application input/output. Note, however, that only one of these functions can be selected. Further details are given in the Function Code Chapter. If mechanical contacts are triggered (i.e. relays, switches, Reed contacts, etc.), the input frequency has to be damped (attenuated) to 30 Hz, so as to filter out bounce pulses.
If damping to 30 Hz is selected, all inputs can be used at 30 Hz. Application – Set to preset 0 Programs the application input to act as a Set Input. The counter is set to Pre set 0, independently of the reset via input C or the keyboard. To reach these values the amplitude thresholds are to be hold. (See technical data - chapter 10) This function is not available for tachometers. Signal P 1 and P 2 are available as relay changeover contacts and electronic output signals (PNP). P 0 is available as an electronic output signal across the application output (PNP). Application keylock: All keyboard functions can be locked (latched) individually (Reset, P 0, P 1, P 2, Prescaler) Lock mode:
release after 10s, complete keylock or keylock depending on keylock input (application input) If a signal is active, this will be shown on the LCD display. Optionally, the multifunctional counter can be set to have the display flash if one or all the preset values are acive. This is also valid for Preset 0 (if no output has been assigned) Our advice! After setting up the system, lock (latch) all the keyboard functions that are not allowed to be changed by the user. Signaltime: 1.) bistable: Cleared by electronic or manual reset. P 0 + P 1= bistable – additionally cleared by signal 2 Attention: Signal 2 must not be bistable for automatic reset. 2.) monostable:
Up to 9 fixed signal times are available between 0,02s and 10s. In addition, user times can be programmed between 0,01s to 599,99s. 3.) Range signals: active as long as the counter reading is within the adjusted range. Signals active on/off During normal operation the relay is energized if the signal is active. This behavior can also be inverted (also applicable to the transistor outputs). 36 37
