7.4.2 Accelerated programming of relay switching
time from 20s to 30 min
In case of accelerated programming, the programming time is
reduced 10 times, the programming step being 10-15 s.
1) Remove the front cover of the receiver (see 9.2).
2) Remove a jumper from the T plug; install jumpers on F1
and F2 plugs.
3) Press the button on the receiver, and while holding it,
power the receiver up.
4) Release the button, and then press for 1-2 s.
5) Wait during the required (programmed) time interval re-
duced 10 times (from 2 s to 3 min), and install the jumper on
the T plug.
6) Power the receiver down.
7) Remove jumpers from F1 and F2 plugs.
8) Close the front cover of the receiver.
7.4.3 Default Setting of Relay Switching Time (2 s)
1) Remove the front cover of the receiver (see 9.2).
2) Install jumpers on T, F1 and F2 plugs.
3) Press the button on the receiver, and while holding it,
power the receiver up.
3) Release the button.
4) Power the receiver down.
5) Remove jumpers from F1 and F2 plugs.
6) Close the receiver cover.
8 Operability Test
8.1 Relay actuation with latching
1) Remove the front cover of the receiver (see 9.2).
2) Remove jumpers from T, F1 and F2 plugs.
3) Connect terminals of the receiver to the indication panel
Astra-931 and a power supply unit as shown in Figure 4.
Figure 4
4) Power the receiver and the indication panel Astra-931 up.
The green indicator of the receiver will blink 1 time per 4 s.,
the red indicator is off.
5) Press the button on the receiver.
The red indicator will be on.
Normally-opened (NO) relay contacts will close.
The indication panel Astra-931 will display the number of the
transmitter which sent the signal. If the battery in the transmitter
is low, the number will blink.
6) Press the button on the transmitter (Figure 3).
The red indicator will be off.
The relays will return to the initial status.
The relay status and the status of the red indicator of the receiver will change with each pressing the button on the transmitter.
7) Power the receiver down.
8.2 Relay actuation with time delay
1) Remove the front cover of the receiver (see 9.2).
2) Install a jumper on T plug; remove jumpers from F1 and F2
plugs.
3) Connect terminals of the receiver to the indication panel
Astra-931 and a power supply unit as shown in Figure 4.
4) Power the receiver and the indication panel Astra-931 up.
The green indicator of the receiver will blink 1 time per 4 s.,
the red indicator is off.
5) Press the transmitter button (Figure 3).
The red indicator will be on, and the relay will be actuated
within the preset time interval.
The indication panel Astra-931 will display the number of the
transmitter which sent the signal. If the battery in the transmitter
is low, the number will blink.
6) Power the receiver down.
WARNING! If you press the button on the transmitter more
than 15 times outside WAS coverage area, the synchronization between the receiver and the transmitter will be
disrupted, and no identification shall occur. To synchronize the equipment again, reenter the WAS coverage area
and press the button on the transmitter 2 times.
9 Installation
9.1 Select Installation Location
9.1.1 The receiver performs best for optimum coverage when
installed at a maximum height (minimum 2m).
9.1.2 Avoid running power supply cables and the interface line
of the receiver close to heavy duty power lines and high –
frequency cables.
9.1.3 Avoid the following locations for the receiver:
- massive metal constructions or closer than 1m from them;
- closer than 1 m from power mains and metal water or gas pipes
which may cause radio interference;
- lower than 1,5 m above the floor;
- inside metal constructions.
WARNING! Do not place the receiver at a distance less than
10 m from another wireless unit (including its antennas),
which is a source of interference for the receiver. Do not
place the receiver at a distance less than 5 m from the computer (system block and display), uninterruptible power
supply unit and other power equipment.
