PAM-199-P
4 Function modes and technical description
4.1
General Information
The PAM-199 is replacing the functionality of several power amplifiers. The functionality can be chosen by the
command FUNCTION (195, 196 or 197). After this selection the settings have to be saved before the module
may be loaded with a previously saved parameter set.
Due to safety reasons the switching takes places within protected conditions.

Description of the LED function
GREEN + YELLOW
1.
Chasing light (over all LEDs):
The bootloader is active. No normal functions
are possible.
2.
All LEDs flash shortly every 6 s:
An internal data error was detected and cor-
rected automatically! The module still works regularly. To acknowledge the error
the module has to be cycle powered.
YELLOW
Both yellow LEDs flash oppositely every 1 s:
The nonvolatile stored parameters
are inconsistent! To acknowledge the error the data have to be saved with the SAVE
command or the corresponding button in the WPC. If the function of the module has
changed via the FUNCTION parameter, all parameters are deleted purposely and set
to default values. In this case the LEDs indicate no error, but a desired state. To
acknowledge please save.
GREEN
Identical to the READY output.
OFF:
No power supply or ENABLE is not activated
ON:
System is ready for operation
Flashing:
Error detected (e.
g. valve solenoid or 4… 20 mA).
Not active when SENS = OFF.
YELLOW
LED in the middle position = Current, Channel A; the intensity is proportional to the
output current
LED in the right position =
Current, Channel B; the intensity is proportional to the
output current
