4. INSTALLATION
Ensure that the mains power supply specifications correspond to the voltage specified on the data
plate of the electrical panel and motor connected, then make the earthing connection before all
other connections.
DRYTEK 1 Mono ►1~230V ± 15% 50/60Hz
DRYTEK 1 Tri ►3~400V ± 15% 50/60Hz
The power line must be protected by a residual current circuit breaker.
Tighten the electrical cables on the relative terminals using a suitable tool correctly sized to avoid
the risk of damage to the fixing screws. Take care if using an electric screwdriver.
The electrical panel is designed for wall-mounting using screws and plugs in the pre-drilled holes at
the corners of the enclosure, or by means of brackets when present.
Install the equipment in areas compliant with the protection rating and ensure that the box is kept
intact when drilling the holes for fitting the cable clamps.
Avoid the use of multicore cables where there are wires connected to inductive loads and power
cables and signal cables such as sensors and digital inputs.
Keep connection cables as short as possible, preventing any twisting of cables which may be harmful
due to inductive effects on the electronic equipment.
All wires used in the cabling must be suitably sized to withstand the load to be powered.

5. CONTROL PANEL
5.1 Luminous indicators and control commands
The DRYTEK 1 electrical panel has been designed for the adjustable protection of 1 motor with dry
running safety control, obtained from the power factor (where “fi” is the timing angle between
current and voltage), without the need for external commands (float or pressure switch).
N.B. The load is activated or deactivated on closure or opening of the normally open
contact C/I1. If no float or pressure switch is used, a jumper must be wired in on
input C/I1.

6. KEY TO FUNCTIONS AND SETTINGS
6.1 Main display items
On activation of the DRYTEK 1 panel, the display shows the following:
At the end of the start-up sequence, the main menu is displayed, as described below.
This screen enables display of the electrical data as read by the DRYTEK 1
panel in real time:
230 V = Power supply voltage reading;
0.0 A = Current absorbed by connected load;
1.00 ϕ= Power factor of connected load;
MAN () = Panel set to manual mode;
AUT () = Panel set to automatic mode;
6.2 Activation of load in manual mode
On activation the panel always starts up in Automatic mode, indicated by the asterisk () displayed
alongside the text AUT on display.
The operating mode can be changed by pressing the UP arrow to change to Manual mode, or the
DOWN arrow to change to Automatic mode.
Therefore, to enable operation in Manual mode, press the UP arrow (the asterisk () is displayed
alongside the text MAN) and then press and hold OK.
The display then displays current absorption of the motor and the power factor values in real time;
the green led also lights up to indicate the electric pump is running.
On release of the OK button, the motor is shut down.
N.B. in manual mode, the load is activated and bypasses all alarms, but in the event
of a fault the display flashes, and the user can press the DOWN arrow to view a
description of the alarm.
