Connecting The Load - TDK-Lambda Genesys User Manual

a) Connect a variable load across the unit output that ranges from 5-15% of rated
Output current. Set the load current to 5% of rated Output current.
b) Ensure that the Output voltage is set to approximately 10% of the unit Output
voltage rating.
c) Adjust the CURRENT encoder to set the current limit to approximately 10% of the
unit Output current rating.
d) Momentarily press the FOLD button. Ensure that the FOLD LED illuminates. The
Output voltage should remain unchanged.
e) Increase the load current from 5% to 15% of rated Output current. Ensure that
the Output voltage falls to zero, the VOLT display shows "Fb" and the ALARM
LED blinks.
f) Press the FOLD button again to cancel the Foldback protection. The Output
voltage should remain at zero.
g) Press the OUT button. Ensure that the Output voltage returns to its last setting.
h) Turn the output Off by pressing the OUT button. The VOLT display should display
"OFF".
3.8.8. Address Setting
a) Press and hold the REM/LOC button for approximately 3 seconds. The VOLT
display will show the communication port Address.
b) Using the VOLT adjust encoder, set the unit Address within the range of 0 to 30.
c) Set the unit Address back to the factory default setting (see Section 8.2.1).
3.8.9. Baud Rate Setting (RS-232 and RS-485 only)
a) Press and hold the REM/LOC button for approximately 3 seconds. The
CURRENT display will show the communication port Baud rate.
b) Using The CURRENT adjust encoder, set the Baud rate to 1200, 2400, 4800,
9600 or 19200.
c) Set the unit Baud rate back to the factory default setting (see Section 8.2.1).

Connecting the Load

Turn Off the AC input power before making or changing any rear
panel connection. Ensure all live circuits are discharged and that all
3.9.1. Load Wiring
The following considerations should be made to select wiring for connecting the load
to the Power Supply:

Current carrying capacity of the wire (refer to Section 3.9.2).

Insulation rating of the wire should be at lease equivalent to the maximum Output
voltage of the Power Supply

Maximum wire length and voltage drop (design for 1V drop per lead).

Noise and impedance effects of the load wire (refer to Section 3.9.4).
3.9.2. Current Carrying Capacity
The load cables between the Power Supply Output and the load must be specified.
The cable connections must be secured to required torque spec. Failure to meet
connections are securely tightened before applying power.
