Camera Interface
2-34 Basler A500k
PRELIMINARY
2.8 DC Power
The A500k requires 12 VDC (± 10%) power. The maximum power consumption is 6 W for the
A504
k/kc, 5.4 W for the A503k/kc, and 3 W for the A501k/kc. The current during constant operation
is 500 mA max. for the A504
k/kc, 450 mA max. for the A503k/kc, and 250 mA max. for the
A501
k/kc. Peak currents may occur. We recommend using 1.5 A power supplies.
The camera is equipped with an undervoltage lockout. The camera has no overvoltage protection.
Ripple must be less than 1%.
2.9 Power Control: Full Function and Standby
The camera can be set into a standby mode with register settings (see section 4.2.11). In standby
mode, the camera’s power consumption is reduced to 2.5 W for the A504
k/kc and A503k, and
1.8 W for the A501
k/kc. The Camera Link output is no longer fed, the sensor does not react any
more. The monitor output available for the A504
k/kc is no longer fed. The camera remembers the
work set configuration. The serial communication is still operable. When the camera is set back
to full function, it takes maximum 0.5 s until it is fully operable. During this startup time, the ExSync
signal is not recognized reliably which can have the effect that the first image is not exposed
correctly.
Power up time after power was off entirely takes a maximum of 3 s.
2.10 Status LED
When the LED on the back of the camera is not lit, it means that no power is present. When the
LED is lit, it means that power to the camera is present.
Keep in mind that the circuit used to light the LED on the camera does not perform a voltage range
check. If power to the camera is present but it is out of range, the LED on the camera may be lit
but the camera will not operate properly.
When the LED on the back of the camera is orange this indicates signal integrity. At power up, the
LED will light for several seconds in orange and sometimes green as the microprocessor in the
camera boots up. If all is OK, the LED will then remain orange continuously.
If an error condition is detected at any time after the microprocessor boots up, the LED will begin
flashing an error code. See section 6 for details.
L
A Hirose plug will be shipped with each camera. This plug should be used to termi-
nate the cable on the camera's power supply.
For proper EMI protection, the power supply cable attached to this plug must be a
twin-core shielded cable. Also, the housing of the Hirose plug must be connected to
the cable shield and the cable shield must be connected to earth ground at the
power supply.
Make sure that the polarity is correct.
