7�- RUN STATUS
Once the device has been configured according to installation needs it can be set to RUN mode
to regulate the PF of the installation. RUN mode is the default mode after exiting the set-up
menu or after the device start (supply connection followed by a short initialisation period). When
the device is in RUN mode it can reach one of the following status:
A�- Normal RUN status (Absence of alarm): In this status the device performs the
automatic PF regulation, connecting and disconnecting the capacitor stages according to
installation needs. In this status the user can access to the measurement of different pa-
rameters and can also force the manual connection or disconnection of capacitor stages
as described in
B�- Alarm status: If any of the anomalous situations described in
ERROR MESSAGES"
Depending on the error type the regulator may perform the disconnection of all the stages
or continue regulating the PF as in normal RUN.
7.1.- FUNCTIONS OF THE DEVICE IN NORMAL RUN MODE.
In the normal RUN mode the computer MAX can perform the following functions:
Manual connection of capacitor stages: Keep the key pushed during more than 1s
and the regulator will sequentially connect the different steps, following the normal pro-
long
gram and respecting the delay time t
Manual disconnection of capacitor stages: Keep the key pushed during more than
1s and the regulator will sequentially disconnect the different steps, following the normal
long program and respecting the delay time t
Displaying the number of connected steps: If both keys are simultaneously pushed
the device displays the Nr of connected steps. Remember the difference between step
and stage ("2.3.3.- STAGES AND STEPS")
Parameters measurement: Performing successive short pushing of this key (<1 s),
the user can travel along several display screens showing the values of the following
parameters: (cos) , cosinus φ of the installation ; (I) , mains current; (THD), THD of mains
current; (V) , Mains voltage; (I, MAX), Maximum value of mains current since the last
short
clear; (V MAX), Maximum value of mains voltage since the last clear.
The displayed parameter is pointed by the cursor
Parameters measurement: Performing successive short pushing of this key (<1 s),
the user can travel through the readings of the same parameters described above but in
short
reverse order.
Start the SET-UP mode: Performing a long push of this key (<1 s), the device jumps to
set-up mode.
long
Clear MAX values: Performing a long push of this key (<1 s) while the cursor
pointing to MAX , the computer MAX clears the maximum values of voltage and current
recorded since the last clear.
