ERMUSA
4.1.1 Transmitter Test and Adjustment
To align and adjust the Transmitter ERMUSA proceed as follows:
- unscrew the specific screws to remove the front cover;
- activate the power supply connection to MS1 terminal block (Fig. 9);
- check that the LED D10 indicating presence of mains lights up.
- preset one of the 4 channels available through the channel selector SW1 (fig. 9).
Connect the STC 95 instrument to the ERMUSA Tx barrier, use the related flat cable (16 wires)
and insert it in
J1
connector.
a) Check that LED
Rx/Tx 1
(22) is lights up. If it isn’t, press the key
“1”
(21) for lights up it.
b) Press the key
“
”
(10) a number of time as needed for lights up the LED
“+ 13,8 V”
(4). The voltage indicated by
display
(2) must be 13,8 V
+ 10%.
c) Press the key
“
”
(10) until the LED
“9V Tx”
lights up
(8).The voltage indicated by
display
(2) must be 9 V + 10%.
d) Press the key
“
”
(10) until the LED
“sens. Rx / Tx”
lights up
(6).
The voltage indicated
by
display
(2) must be 4,5 V
+ 10%.
4.1.2 Receiver Test and Adjustment
To align and adjust the Receiver ERMUSA proceed as follows:
- unscrew the specific screws to remove the front cover;
- connect the power supply to terminals 1 and 2 of MS1 terminal block (fig. 10);
- check that the LED D 10 indicating presence of mains lights up;
-
preset one of the 4 channels available through the channel selector SW1, same as
channel preset on Transmitter unit.
Connect the STC 95 instrument to the ERMUSA RX barrier as shown in Fig. 12. Insert the
seven pins connector into the connector
J1
present on Receiver circuit (fig. 10).
a)
Check that LED “
Rx / Tx
1”
(22) is lights up, If not press the key
“1”
(21) for lights up.
b) Press the key
“
”
(10) a number of time as needed for lights up the LED
“+ 13,8 V”
(4). The voltage indicated by
display
(2) must be 13,8 V + 10%. Go on the rear part of
receiver head and verifies that the path is free from moving obstacles. If the previous
visual system alignment is correct, check that the LED D1 (channel identification) are
lights up (Fig. 11).
For the path optimisation go on with electronic alignment, see next:
c) Check that the LED
“On”
(16) is off. If not, press the key
“buzzer”
(15), for turn the
LED off, this force the STC 95 internal buzzer not active.
d) Check that the LED
"open"
(18) is light up, if not press the key
“loop”
(17), for the
“loop”
opening and turn on the LED.
e) Press the key
“
”
(10) until the LED
“Field Rx”
(5)
lights up. Check that a 6 V 10 %
voltage is read on the display and that the mid LED is glowing on the
LED
(3).
Should the voltage value differ and should the glowing LED be the end ones, then press
either key
“ gain”
(11) or key
“ gain”
(12), till the previously described condition
arises (i.e., the LED in the middle of the bar lights up, and a 6 V
10 % value is
read on the display).
