7 AK Host Operation
32
7.5.3.
Read Commands – 'A'
ASTZ
STATUS – read the current operation mode and system state
three modes inform if the system is manually or remote controlled by current
or another host
if system is remote operated by current host, system state is indicated
command: ASTZ K0
response:
ASTZ E OOOO SSSS
E: error status 0...9
OOOO: operation mode:
'SREM': remote operation, current host
'SMAN': manual operation
only read commands possible
'SRBS': remote busy another host is in
remote mode (SREM)
SSSS:
system state:
'SPAU' pause state
'STBY'
standby state
'SMGA' measurement state
'SNGA' zeroing state
'SLEC'
leak test mode
ASTF
ERROR STATUS – read the numbers of all current failures
command: ASTF K0
response:
ASTF E a b c d ...
E: error status 0...9
a, b, c, d ... sequence of the numbers of
current system errors which are listed in
chapter ??. example: '11 13 20' means:
– ET temperature wrong
– CPC not ready
– CPC liquid level too low
AKON
read the current diluted and undiluted particle number concentration:
concentration is corrected to the currently set standard conditions (ENOR)
command: AKON K0
response:
AKON E CCC RRR FFF
E: error status 0...9
CCC: particle concentration corrected to std.
cond. [#/ccm]
E-format: example: '3.26E3'
=
3'260
#/ccm
response is not affected by stopped disk
rotation
RRR: concentration CCC multiplied by PCRF
E-format: example: '3.26E5'
=
326'000
#/ccm
if disk rotation is stopped, response will be
'NaN'
FFF: particle concentration reduction factor
PCRF format: floating point example: '100.0'
if disk rotation is stopped, response will be 'Inf'
APRF
read current particle concentration reduction factor PCRF
command: APRF K0
response: APRF E FFF
E: error status 0...9
FFF: particle concentratio reduction factor
PCRF format: floating point example: '100.0'
if disk rotation is stopped, response will be 'Inf'
