11G3 Cabinets - Service Manual
OS3 Auxiliary Probe 3 oset
D3A
‘DI3’ activation ‘OPN’ - on open
‘CLS’ - on close
AHM
Operation in alarm when ‘T3A’
= ‘CND’
‘NON’ - Audible and visual alarm is inhibited
‘ALR’ - when ‘T3A’ = ‘CND’ and temp. > ‘AHT’ condenser high temperature ‘HC’ alternates in
the display and the alarm sounder is activated
‘STP’ - in addition to the alarm signal, the compressor is stopped and defrosts are
suspended
AHT
Condenser temperature alarm
(referring to TAuxiliary probe)
TLD
Delay for minimum
temperature (‘TLO’) and
maximum temperature (‘THI’)
logging
With ‘TLD’ = ‘0’ the logging is disabled
TDS
The temperature probe value
to be displayed
‘TA’ - actual Tair (T1) value
TAS’ - actual Tair (T1) value slowed (rate of change toward setpoint = actual value, away
from setpoint = mathematical algorithm applied)
‘A-E’ - the AVG-weighted average between TAir (T1) and TEvaporator (T2) probes
‘T3’ - TAuxiliary (T3) probe value (when ‘T3A’ = ‘DSP’, ‘CND’ or ‘2EU’)
SIM Display slowdown. Active when ‘TDS’ = ‘TAS’, the SIM value is the controlling arithmetical value.
AVG
The relative weight of T2 in
respect of T1 (when ‘TDS’ =
‘A-E’)
SCL
Readout scale ‘°C’ with non adjustable resolution in User Function Menu
‘°C’ with adjustable resolution in User Function Menu
‘°F’ with non adjustable resolution in User Function Menu
‘°F’ with adjustable resolution in User Function Menu
PRT Modbus communication type RTL or ASCII
ADR
FD1-19 address for PC
communication
RFP
Return to Factory Parameters. Allow options through ‘User Menu’ to reset all controller parameters to factory production
values where controller has been programmed by Foster
