1 INTRODUCTION

1.1Introduction

EVBOX1 is a line of front mounted electrical boards for the management of cold rooms with single-phase compressor. The user interface comprises a large custom display (with decimal point and function icons), six keys, and has a guaranteed IP65 protection grade front part.

The boards are equipped with two 30A res. @ 250 VAC relays for the direct control of high power compressors and defrosting elements, with no need for remote control switches. They can operate in conditions of both low and high relative humidity percentages, have an adaptive management of the defrost function, and can implement energy-saving strategies. Some models are also equipped with a magneto-thermal switch or differential magneto-thermal circuit breaker, a clock (to save the HACCP alarms), management of defrosting elements and have an integrated driver for unipolar stepper electronic expansion valves.

The unit is designed to be wall mounted, with bolts and fastening screws.

6 USER INTERFACE

6.1Preliminary notes

Operating Statuses:

-“on” state (the device is powered and is on: the regulators can be switched on)

-“stand-by” status (the device is powered but is switched off via software: the regulators are switched off; the possibility to turn the room light or the auxiliary output on/off manually depends on parameter u2)

-the “off” status (the device is not powered).

Hereafter, with the word “start-up” means the passage from “stand-by” status to “on” status; the word “shutdown” means the passage from “on” status to “stand-by” status.

When the power is switched back on, the device displays the status that it was in at the time it was disconnected.

6.2Device switch-on/off in manual

mode

To turn the device on/off in manual mode, proceed as follows: 1. Make sure that the keyboard is not locked and that

no procedure is in progress.

2. Hold the key “ON/STAND-BY” for 2 s.

Using the digital inputs it is also possible to remotely switch on/off the device.

6.5 "Rapid cooling" function enabling/disabling

To enable/disable the "rapid cooling" function, proceed as follows:

1.

Check that the device is turned on, that the

 

keypad is not locked, that no procedures are in

 

progress and that there are no defrosting, dripping

 

or evaporator fan stop operations in progress.

2.

Keep the "UP" key

pressed for 4 s: the

"Rapid cooling" function enabling/disabling

"temperature" LED light shall start flashing.

page 25 of 88

EVCO S.p.A.

During the "rapid cooling" function the work set point is decreased by the temperature set with the r5 parameter; the function runs for the span of time set with the r6 parameter.

During the "rapid cooling" function the defrosting function is never activated; if the defrosting interval expires while the rapid cooling function is in progress, the defrosting shall be activated at the end of the cooling.

6.6Defrosting manual activation

To activate the defrosting in manual mode, proceed as follows:

1.Check that the device is turned on, that the keypad is not locked, that no procedures are in progress and that the "rapid cooling" function is not in progress.

2.Keep the "DEFROSTING" key pressed for 4 s.

If the evaporator temperature sensor functions as a defrosting sensor (that is to say,if the P3 parameter is set to 1) and when the defrosting starts the evaporator temperature exceeds the value set with the d2 parameter, the defrosting shall not be activated.

6.7 Turning on/off of room lights manually (only if the parameter u1 and/or parameter u11 is set at 0)

To turn the room light on/off in manual mode, proceed as follows:

1.Make sure no procedures are in progress.

2.Press and release the "AUXILIARY" key: the "room light" LED shall turn on/off.

Through the digital ports it is also possible to turn the room light on/off from remote; see parameter u2.
