Time relays are used for time control in industrial and home automation systems (e.g. ventilation, heating, lighting, signaling, etc.).
*OFF DELAY (A)
Until the relay is switched on, the contact remains in position 11-10 (3-5 for PCU-511 UNI). After applying the supply voltage, the contact is switched to position 11-12 (3-7 for PCU-511 UNI) and the set operating time t is measured.
After the time t has measured, the contact returns to position 11-10 (3-5 for PCU-511 UNI). The relay can be switched back to the operating mode after disconnecting the supply voltage and then reconnecting it.
*SWITCH-ON DELAY (B)
Before and after applying the supply voltage, the contact remains in position 11-10 (3-5 for PCU-511 UNI) and the set operating time t is measured. After the time t has measured, the contact is switched to position 11-12 (3-7 for PCU-511 UNI).
The relay can be re-entered into its operating mode after disconnecting the supply voltage and then re-connecting it.
*DELAYED OFF - CYCLIC (C)
The delayed off operating mode is carried out cyclically at equal intervals of the set operating and break times.
*DELAYED ON - CYCLIC (D)
The delayed on operating mode is carried out cyclically at equal intervals of the set operating and break times.
* Setting the time range rotary switch to the ON position with the power supply on causes the contact to be permanently closed in position 11-12 (3-7 for PCU-511 UNI).
OFF when the power is on causes the contacts to be permanently switched to position 11-10 (3-5 for PCU-511 UNI).
* When the power is on, the system does not respond to changes in the time range settings.
* Operation with the newly set time range takes place after switching the power off and on again.
* With the power on within the set time range, smooth time adjustment is possible within the time setting value.
