6.3 Automatic Conversion of Units of Measurement
By modifying parameter G07, on the next device restart all temperature and pressure parameters will be converted.
Value G07
Temperature unit of measurement Pressure unit of measurement
0
°C
1
°F
To render the parameter modification effective, the device must be left unpowered for 10 seconds before switching back on.
6.4 Restoring Default Parameters
At the "installer" level, it is possible to restore the default parameters (contact TEXA authorised personnel).
6.5 Connection in Sequence of Two Units
Two units can be connected in sequence using a dedicated cable (optional accessory).
The communication between the two units is established by setting the parameter G20=1 on both machines (menu PAr, general parameters PG).
In the event that there is no communication between the units, the error message "CoM" will be displayed on the main screen.
6.6 Behaviour Following a Generic Alarm (ALL): door contact open or other remote contact (PIN 4-5 alarms connector)
Following opening of the external contact, the behaviour of the unit will depend on the value of parameter A85:
A85=0: generic alarm immediately shuts off all components (compressor, evaporator fan and condensing fan)
A85=1: generic alarm immediately shuts off all components with the exception of the evaporator fan
6.7 Alarm Relay Behaviour (PIN 1-2-3 alarms connector)
The behaviour of the alarm relay in response to the various fault conditions will depend on the value set for parameter A84:
A84=0: generic alarm DOES NOT switch the alarm relay; maintenance alarms DO NOT switch the alarm relay
A84=1: generic alarm switches the alarm relay; maintenance alarms DO NOT switch the alarm relay
A84=2: generic alarm DOES NOT switch the alarm relay; maintenance alarms switch the alarm relay
A84=3: generic alarm switches the alarm relay; maintenance alarms switch the alarm relay
6.8 Alarms
6.8.1 Low/High Regulation Temperature Alarms
The intervention thresholds of the low and high regulation temperature alarms may relate to the regulation Set Point or be absolute values on the basis of
the value of parameter A86 (choice of High/Low Regulation Temperature alarm threshold type):
A86=0 = thresholds relating to the regulation Set Point
A86=1 = absolute thresholds A87, A88:
• A87 High Regulation Temperature alarm absolute set point
• A88 Low Regulation Temperature alarm absolute set point
6.8.1.1 High Regulation Temperature - Hrt
This alarm is generated if the regulation sensor exceeds the value (COO+A16)+r01 if the relative set points are used (A86 = 0), or A87+r01 if the absolute
set points are used (A86 = 1) for a time A17. It is cancelled when the regulation sensor falls below the value COO+A16 if the relative set points are used
(A86 = 0), or A87 if the absolute set points are used (A86 = 1). Warning only.
