3. Lokaset R – Installation
The Lokaset R central unit (Figure 1) is installed in a dry indoor
location. A good installation location enables easy reading and
control of the device. Do not cover the central unit as this may
interfere with signal reception from the transmitter. The Lokaset
R central unit is mounted on a wall with screws through the ho-
les at the bottom of the device. The lid of the housing must be
opened for installation. The device is plugged to the 230 V mains
via the power cord.
Operation of the probe and the transmitter should be tested du-
ring installation in order to ensure that the radio signal can travel
freely. Activate the transmitter test mode (see Service instruc-
tions, p. 8). Immerse the measuring head momentarily in water.
If the central unit is operational, the blue light (SIGNAL) should
turn off every 8 seconds and the alarm should be signalled within
8 seconds.
Installation of the Lokaset R transmitter is illustrated on the adja-
cent page. The transmitter is installed on the cover (1) of the
tank’s outlet pipe using the provided plate screws (2); 4 pcs, 2.9–3
x 25 mm.
Place the rubber gasket (3) between the transmitter and the co-
Kuva 1.
ver. The cover of the transmitter must be opened for installation.
Make a lead-through for the cable (4) or for the entire probe in the
cover of the outlet pipe.
Connect the probe cable conductors to the screw terminals (5)
on the transmitter circuit board. The polarity of the cable connec-
tion has no signifi cance to device operation. Tighten the probe
cable gland (6). Install a cable tie above the cable gland as a cable
clamp. Place the supplied battery CR123A in the battery compart-
ment (7) with the positive pole (+) facing upward. Correct installa-
tion of the probe cable and battery is illustrated on page 8.
