1. INTRODUCTION TO ZLIDISPLAY
ZLIDISPLAY allows to show the basic parameters of the battery to which it is connected:
• State of charge or S.o.C.
• Total voltage
• Charging or discharging current
• Maximum internal temperature
• Remaining autonomy according to discharge current
Direct communication with BMS makes it a very precise and essential accessory for knowing the state of the
battery.
NB: ZLIDISPLAY works exclusively with Zenith Lithium batteries.

2. HOW TO CONNECT THE DISPLAY TO THE BATTERY
3. ON/OFF BUTTON
4. WORKING DURING CHARGING
On the back of the display and the battery have the same RS485 communication port.
It will be necessary the appropiate ZLIDISPCABx cable in order to connect both devices.
The ON/OFF button is used to switch the display on or off.
Press and hold the ON/OFF button for about 5 seconds to switch the display on or off.
"Charging" will appear on the display during charging phase and the charging current will be indicated at the
bottom right corner.
After 2 consecutive minutes in the charging phase, the display automatically goes into stand-by mode.
Press and hold the ON/OFF button for about 5 seconds to switch it on again or discharge the battery.
NB: the display only works when the battery is switched on

5. OPERATION DURING DISCHARGE
6. WHAT IS THE PURPOSE, HOW DOES BLOCKING RELAY WORK AND WHAT ARE ITS TECHNICAL CHARACTERISTICS
"Discharging" will appear on the display during the discharging phase, the discharge current will be indicated at
the bottom right corner and in the centre there will be the remaining autonomy time depending on the discharge
current (if the remaining autonomy is more than 100 hours, the display will show "TIME --:--").
During this phase the display will never go into stand-by mode but it will be possible to switch it off by pressing and
holding the ON/OFF button.
During discharging, when the S.o.C. of the battery falls below 20%, the blocking relay is activated.
It is deactivated when during the charging of the battery, the S.o.C. reaches and exceeds 50% (the two values are not
programmable).
The block relay is used to disable one or more vehicle functions.
When the lock realy is active, "Lock Relay" appears on the display.
This is the connection diagram:

As soon as the S.o.C. reaches 20% the battery icon will change from green to red.
As soon as the S.o.C. reaches 10% the display will start flashing.
On models ZLI012035, ZLI012051 and ZLI024036 the display will switch off until the battery is charged, in case of full
discharge (S.o.C. = 0%).
On all the other models it will remain on and continue to flash.
