7 Key, Timer or Permanent Connection Switching Functions
After specifying which transmitter key will control the relay, the next step is to
set the time for the relay function.
The connection duration or the disconnection delay can be selected individually for each channel via the 6
switches (see Figure 1: Timer setting). Table 2 shows all possible values; factory pre-set values are printed in
bold.
If the user requires a channel with key-function, the shortest time in Table 2 should be used. The
corresponding relay will stay closed only as long as the transmitter key remains active.
Caution: If due to electromagnetic interference during the switching process (e.g. from inductances), short
transmitter interruptions occur (which may be perceived as relay bouncing), the timer setting can be increased
in steps. These times that can be considered as falling delays, avoiding the undesirable „bouncing" effect of
the relay contacts. Normally, values up to 0.8 s are sufficient.
Higher timer values adjustable up to 60 minutes allow the user to program the connection of any devices for a
specific length of time.
Furthermore, a steady connection (continuous ON) can be selected as well. The disconnection (power OFF)
can be performed with a separate signal, i.e. a separate transmitter key.
If instead of or in addition to a wireless control, the relay needs to be switched on/off by means of a wired
connection, the contact +U (positive supply) can be used to produce a corresponding „ON" command to
contact "Ext.-ON" by means of an external push-button (not included in delivery). In case of AC one of pole of
supply is sufficient.
8 Antenna
The receiver SHR-7 K1 is equipped with an integrated antenna that has optimal reception characteristics.
Ensure that the antenna is mounted as far as possible away from power wiring and is not in
contact with any powered part, particularly in the terminal connection area.
