Handling And Storage - DAB ESC plus 3M Instalación Y Mantenimiento

In the event of dry operation (no water), the system automatically carries out 4 tests with increasingly longer
pauses in between (10, 22, 45, 90 minutes), in order to allow the water level in the well to be restored, and
signalling the stand-by state with the indication SB on the display. If the presence of water is detected during one
of the tests, the alarm is reset and ESC plus continues with normal operation.
If there is still no water after 4 tests, ESC plus gives the alarm with the indication UL (under load) on the display
and remains locked until a manual reset is carried out (see 3.2.13).
A capacitor of suitable size has to be inserted and connected in single-phase versions.
The system may be connected to external automated systems such as pressure switches, floats, alarm signals,
timers, computers, etc. through an electrically clean (not live) NC contact connected to the SW terminals on the
main terminal board.
3.1.1 ATTENTION!: should this possibility not be used, leave the short circuit jumper (2) between the
two
3.2 STATE:
ESC plus indicates the operating state of the system by displaying, through display, the following situations:
Calibration and normal functioning.
3.2.1 Self-diagnosis upon start-up (indication of the frequency).
3.2.2 Display of automatic calibration (display of text AT).
3.2.3 Display of learning phase (display of text CL).
3.2.4 Display of manual calibration (display of text MA).
3.2.5 Display of current value setting (display of text AA).
3.2.6 Display of power factor setting (display of text CP).
3.2.7 Normal operation (indication of the absorbed current).
Error condition.
3.2.8 Situation of dry operation/low load (display of SB blinking).
3.2.9 Stand-by for restoring of level (display of SB, load disconnected).
3.2.10 Final lack of water, (display of UL , load disconnected).
3.2.11 Overload in progress (display of the absorbed current blinking).
3.2.12 Overload alarm (display of the OL blinking, load disconnected).
Before restarting ESC plus, remove any error condition on the control panel by switching it off
3.2.13
and then on again (1).

HANDLING AND STORAGE:

Make sure that the unit has not undergone any damage during shipment and that is still in its original packaging
without penetration of water or humidity.
Store the unit in a dry and aerated place.
5 INSTALLATION:
Check to make sure that the rating place data (power/size and voltage) are correct as ordered and that
they are compatible with the load/motor that the ESC plus must control.
An appropriate knife switch that guarantees the visual opening/disconnection of the same from
the power supply line, thereby guaranteeing the intervention of the operator on the panel in maximum
safety.
ESC plus should be installed, if possible, in the shade, as near as possible to the motor, in an upright
position and making sure that the cable clamps are in the bottom position.
The container is rated IP44, but protection is guaranteed only if installation is correct.
