5. Initial setting

5.1 Setting procedure / Input signal level

1. Setting procedure
Power OFF
Setting of DIP switch
( See page 5.)
Power ON
Adjustment of input signal level
Adjusutment of non-linear
characteristic
Special setting
2. Input signal level
The adjustment is executable at any time, and it is validated when the DIP SW1 is turned on, SW2 is
turned off, SW3 is turned on and the power source is closed.
Power

SET
MODE
Turn on the DIP SW1 to set the power amplifire mode.
•
Turn on the DIP SW4 to SW10 to set the output to full-scale (
•
0.2 to 0.4A ) or 24VDC.
When the DIP SW2 and SW3 are turned on, the output is de-
•
fined to be set to 0 to 5V.
When the DIP SW2 is turned on and SW3 is turned off, the out-
•
put is defined to be set to 0 to 8V.
When the DIP SW2 is turned off and SW3 is turned on, it is pos-
•
sible to adjust the input signal level to 0 to Vmax (Vmax = 0.5 to
8V ). The adjustment procedure in this case is described as be-
low.
Set the non-linear characteristic in accordance with the proce-
•
dure shown on the next page. It is teated as a linear character-
istic unless the setting is made.
Set the [RC] input logic, stop gain, stop bias, stop timer and
•
aux.power output timer as reqierd in accordance with the pro-
cedure given on page 25, 26.
Output
When the power source of LE-50PAU is closed, the output cur-
•
display
rent or output voltage is displayed soon in accordance with the
sequence shown on page 23.
MODE
When the [MODE] key is pressed with the [INC ] key pressed,
•
INC
the input signal level adjustment mode is turned on.
[ L ] indicate that the input signal level adjustment mode is
•
turned on, in which the current adjustment value is indicated.
Press the [INC ] key or [DEC ] key several times to display
•
the target tnput signal level ( 0.5 to 8.0V ).
When the key is kept pressed, the numeric value is incremented
or decremented at high speed automatically.
The drawing given at left shows a screen of numeric value dis-
•
played by operation of [INC ] key or [DEC ] key, in which the
value is set to 4.3V for instance.
MODE
INC
When the [SET] key is pressed, the numeric value set in this
•
case is updated and stored in the EEPROM memory within the
LE-50PAU power amplifire.
When the [INC
input signal adjustment mode is reset.
If only the [MODE] key is pressed before the operation, it is pos-
•
sible to correct the input signal level again.
