Information item configuration on the display:
This configuration determines the item shown on "information" on the user menu (page 00):
Network Address: the network address set up for the compressor (standard)
Machine Status Number: the active actual condition of the block status (see diagram of machine status)
Average Variation Time: the average variation time of the software control in ms (milliseconds).
Registered Start-ups: The number of motor start-ups that occurred in a one-hour period.
The "information item" was designed for general information or diagnostics purposes; to disable, select (0).
Automatic restart:
If an automatic restart time is specified, the interface will execute an automatic restart-up after a power loss if the compressor was opera-
ting when the power loss occurs. The delay time specifies the warning period after the interface initialization, before the restart is executed.
The time before the restart is indicated on the display.
No restart will occur if the interface is not in the Start status before the power loss.
Start-ups per hour:
Every time a start-up event of the main motor occurs, an entry is registered.
To disable this function, and keep the adjusted time for the period until the operation, regardless the motor start-up events, set the configu-
ration of start-ups per hour to 0 (zero).
Analog Output Selection:
In the standard mode for the fixed speed on the motor, the analog output can be selected to follow the line pressure "14", the outlet tempe-
rature "15" or the internal pressure "16". To disable the output, select "0".
The analog output can also be used to power an auxiliary relay; this relay's contacts can then be used to alternate between the remote
devices.
Configurations: 1 to 13 = same functions described for the options R5 and R6 from 1 to 13
Use only a 24Vdc relay that has an interrupter and does not accumulate current superior to 20mA.
Note: In the variable speed control modes, the analog output will be the 4-20mA control signal of the frequency inverter.
In this case, the analog output will show the configuration "17" (variable speed control); the configuration will be locked and not able to be
adjusted.
Unpowered for any active alarm (excluding Start-up/Operation Impediments)
Unpowered for any active shutdown fault (excluding Start-up/Operation Impediments)
Unpowered for any Alarm and Start-up/Operation or Shutdown Impediments.
Powered when temperature drops below the level adjusted for operation temperature impediment (+2°C).
Unpowered when temperature rises above the level adjusted for operation temperature impediment (+3°C).
Can be used to power the interrupter of the anti-condensate or an auxiliary output for low-temperature warning.
Powered in every operation status, except during the start-up of the compressor.
Enabled to operate in all OPERATION statuses, except during start-up. If enabled to operate, the output will be powered only if the
outlet temperature exceeds the "FH" temperature setting. If the outlet temperature drops below the value adjusted for "FL", the
output will be powered off. Once powered, the output will remain powered for at least the "Fan Minimum Operation Time (FT)",
regardless the outlet temperature. Can be used to power the fan motor interrupter; the minimum operation time was designed as
Unpowered when maintenance alarms are active.
Powered only when maintenance services are needed.
Enables and disables drain function.
Can be used to power the interrupter of the fan motor.
Powered in Standby status.
Powered in all OPERATION conditions.
Powered in all LOAD conditions.
Powered every time the compressor is starting-up.
a means to limit the number of fan motor start-ups.
