Keypad / LCD Option
3.1
Introduction
Every hydroSpider has built-in support for a two-line display and a
three-key keypad. The keypad and the LCD are used for quick
operational checks and basic setup. Its convenience lies in the fact
that using it requires no external equipment such as laptop
computers or mobile phones.
Normally, the Keypad / LCD is factory fitted. However, you can order
this option and retrofit it yourself at any time. If purchased later, a
new Keypad / LCD hydroSpider lid will be supplied. You can simply
replace the existing lid and plug the cable into the hydroSpider
mother board. The hydroSpider will automatically recognize the new
option when next powered up.

Using the Keypad and Display
The Keypad / LCD is normally turned off and consumes no power. Pressing and holding any of the
keys for approximately one second turns the display and its backlight on.
In order to conserve battery power, the display will automatically turn off after two minutes of key
press inactivity. The shutdown happens in two stages – firstly the backlight turns off to indicate that
the display is about to switched off, and secondly after approximately another 30 seconds the
display will completely turn off.
Normally, the display shows:

the count to zero.
