Timing relays PCS-519 DUO

PCS-519 DUO

Timing relays are devised to time the control of industrial and domestic automatic control engineering systems (e.g. ventilation, heating, lighting, signalling, etc.).
10 functions with START and RESET control input.

Functioning
The relay performs a function selected in accordance with the regime set period. The choice of a specific range of time and work the relay function is to set the appropriate combination of rotary coded switches.

Functions



DELAYED ON
After applying the supply voltage (U green LED is on), the output remains open and the set operating time "t" is measured. After measuring the time "t", the output switches on (red LED is on). Re-execution of the relay operation mode is possible after disconnecting the supply voltage and switching it on again.
     
 



DELAYED OFF
Until the relay is switched on, the output remains open. After applying the supply voltage (green LED is lit) the output will be closed
and the set operating time "t" is measured (red LED illuminated). Re-execution of the relay operation mode is possible after disconnecting the supply voltage and switching it on again.

DELAYED ON - CYCLIC
The mode of operation of the delayed switching is carried out cyclically at equal intervals of the set working time and break.

DELAYED OFF - CYCLIC
The mode of operation of the delayed switching off is carried out cyclically at equal intervals of the set working time and break.

Generation of a single pulse with time "t" on the rising edge of the START signal. During the timing, the system does not respond to START pulses.

Generation of a single pulse with time "t" on the falling edge of the START signal. During the timing, the system does not respond to START pulses.
    
 

FF PCS-516 diag H.gif

Delay on switching off with the possibility of sustaining. The rising edge of the START signal causes the relay to be activated, while the falling edge causes the timing to start. Entering the START signal during timing causes the cycle to be extended by another time "t" with a falling edge.

Generation of a single pulse 0.5 s after the time "t" triggered by the falling edge of the START signal.

Turning off the relay for a specific time "t" with the rising edge of the START signal. During the timing, the system does not respond to the START signal.


 

Attention!
*Setting the time range knob regulator in the:
 ON - position with power supply activated results in the permanent closure of the contact in position 3-7 (UNI) and 11-12 (DUO).
 OFF - position (power supply activated) causes the contact to be permanently closed in the position 3-5 (UNI) and 11-10 (DUO).
*With the power supply on, the system does not respond to the modification of time range and operation mode.
*The newly set time range and operation mode values are active after the power supply is turned off and on or after the RESET voltage is supplied.
* With the power supply on, it is possible to regulate the preset time freely within the selected time range.
*If the function is changed into F, G, H, I, or J, one with the power supply on, and the START voltage is supplied, the system will carry out the previous function and then reset (switch into the newly selected function). A further instance of the START voltage supply will result in executing the new function.
