Kipp&Zonen 2AP Sun Tracker - Manual (Page 91)

REFERENCE INFORMATION
90
The 8 flags are interpreted as follows:
• bit 0 instrument is searching for reference.
• bit 1 instrument is operating autonomously.
• bit 2 instrument is below permissible operating temperature.
• bit 3 unused.
• bit 4 unused.
• bit 5 unused.
• bit 6 unused.
• bit 7 unused.
The instrument states are:
• 2 the instrument has failed its RAM test sequence.
• 3 the instrument has failed its ROM test sequence.
• 4 the instrument failed to find a limit sensor.
• 5 the instrument failed to find a reference sensor.
• 6 the FU parameter is not set.
• 10-13 Calculating sun position and pointing at sun, if possible.
• A the instrument is waiting for certain conditions to be met before proceeding.
These conditions are:
- temperature must reach an appropriate level;
- there must be no alarm signal for either motor. See MS response: bit 1;
- reasonable LL command data must be loaded.
• B to E the instrument is resetting (see CL, HO & WA).
• F the instrument is accepting motion commands (not operating autonomously).
Note: Other state field values are for troubleshooting only and should be ignored.
LOg
Retrieves the next log item from the circular queue. Returns LO where is one
of the messages listed in section 6.6.
LOg
Repositions the location in the circular queue from which the next will be drawn. Returns
LO. There are two alternatives for . 0 positions to the oldest entry in the circular queue. 1
positions to after the newest entry in the circular queue.
MStatus
Retrieves status of all motors. Returns MS . The status values are in
hexadecimal notation and are divided into a set of 8 flags (bits 0 through 7) and a state field (bits 8
through 15).
The 8 flags are interpreted as follows:
• bit 0 motor is in motion.
• bit 1 motor Hardware Alarm is activated.
The state field values are interpreted as follows:
• A finding sun.
• B following sun.
Note: Bits 2 through 7 and other State field values are for troubleshooting only and should be
ignored.
