LIMIT THRESHOLDS (LIMx)
– The LIMx limit thresholds are internal variables the status of which depends on a measurement performed by the soft starter exceeding the limits defined by the user (e.g. total active power higher than 25kW).
– To speed up setting considering that each threshold can span across an extremely wide range, each threshold can be set to a base value and a multiplying coefficient (e.g.: 25 x 1k = 25000).
– Two thresholds are available for each LIM (upper and lower). The upper threshold must always be set to a value higher than the lower value.
– The meaning of the thresholds depends on the following functions:
Min function:
with the Min function the lower threshold is the tripping threshold and the upper threshold is the resetting threshold. The limit is activated after the set delay when the value of the selected
measurement is under the lower threshold. Reset is activated after the set delay when the value of the measurement is higher than the upper threshold.
Max function:
with the Max function the upper threshold is the tripping threshold and the lower threshold is the resetting threshold. The limit is activated after the set delay when the value of the selected
measurement is higher than the upper threshold. Reset is activated after the set delay when the value of the measurement is lower than the lower threshold.
Min+Max function:
with the Min+Max function both the upper and the lower thresholds are trip thresholds. The limit is activated after the respective delays when the value of the selected measurement is either
lower than the lower threshold or higher than the upper threshold . Resetting is immediate as soon as the value returns within the limits.
– Tripping may mean energising or de-energising the LIM limit according to the setting.
– If the LIM limit is programmed with latch, manual resetting is possible using the specific control in the commands menu.
– See the menu P10 Limits.
REMOTE VARIABLES (REMx)
– The ADXL can manage up to 8 variables controlled remotely (REM1…REM8).
– The status of these variables can be edited as required by the user by means of the communication protocol and may be used in combination with outputs.
– Example: a relay can be freely activated and deactivated with the control software by using a remote variable (REMx) as source of an output (OUTx). This would allow you to use the ADXL output relays to control
user devices.
– Another use of the REM variables may be to enable or disable given remote functions, for instance to generate alarms or messages remotely.
USER ALARMS (UAx)
– The user can define up to 4 programmable alarms (UA1…UA4).
– For each alarm you can configure:
• the source, i.e. the condition which generates the alarm ;
• the text of the message which must appear on the display when the condition occurs;
• the properties of the alarm (like for the standard alarms).
– For example, one condition which generates the alarm could be a measure which goes beyond a limit threshold. In this case, the alarm source must be one of the limit thresholds (LIMx).
– Differently, if the alarm must be displayed as a consequence of the activation of an external digital input, then the source will be an input INPx.
– The user can define a freely editable message which will appear in the alarm pop-up window.
– Properties can be defined for the user alarms using the same method applied for standard alarms. In other words, it is possible to determine whether a given alarm must stop the motor, close the global alarm
output etc. See the Alarm properties chapter.
– Multiple simultaneous alarms will be displayed in sequence.
– To reset an alarm programmed with latch enabled, use the specifc command of the Command menu.
– See menu P13 User Alarms for the configuration of user alarms.
IR PROGRAMMING PORT
– The ADXL's parameters can be configured via the front optical port, using the IR-USB CX01 programming adapter or the IR-Wi-Fi CX02 adapter.
– Simply approach a CX.. adapter to the front port and insert the plugs in the specific holds to obtain the mutual recognition of the devices, as indicated by the green LINK LEDs on the programming adapter.
– Both adapters CX01 and CX02 can be used for the connection of the soft starter to Xpress remote control and configuration software.
– Through the Wi-Fi adapter CX02 (Wi-Fi) is also possible to connect to the App Lovato Electric SAM1.

PARAMETER SETTING FROM PC
– With the Lovato Electric Xpress remote control and configuration software is possible to read and modify the parameters of the ADXL and save them on a file on the hard disk of the PC, or alternatively you can
upload a parameters file from the PC and download it into the soft starter ADXL.
– The connection of the ADXL soft starter to the software Xpress can be made via the front optical port (with USB adapter CX01 or Wi-Fi adapter CX02) or by using the optional RS485 card (code EXC 1042).
– In addition to the parameters setting, with the software Xpress you can also monitor the measures of the ADXL on pre-configured graphical indicators, read events and create graphical trends for the real-time
monitoring of the variables of the soft starter.
