OPERATION
The Neos 100S unit is an all-electrical unit, powered by the vehicle battery (alternator).
After starting up the refrigeration unit by pressing the ON key, the microprocessor manages the unit regulation
according to the box temperature needed.
The unit automatically shuts down when the engine is switched off with the ignition key.
The unit can be completely shut down manually by pressing the OFF key on the Cab Command.

STANDBY MODE
The Neos 100S is powered by a standby module reducing the 230 VAC into 12 Vdc. The power network connec-
tion is detected by the standby module which automatically starts up the unit in standby mode.
If the ignition key is switched ON while the unit is connected to the power network, or if the standby plug is connected
while the unit is running, a buzzer alarm will sound indicating the double power supply and the unit stops.
For safe, reliable operation in Standby mode, it is important to follow a few guidelines:
•
ALWAYS
check that the unit is OFF (Cab command) before connecting or disconnecting it from the power
source.
• The extension cable and fuse used for network connection must comply with the legislation currently applicable on
the site of use and with the unit specifications as described in the table below:
• The unit connection cable must be fitted with a ground connection. The cable must be connected to earth
(ground).
• On the 230 V supply, the unit should be connected to a Ground Fault Protection Device.
• Operations on the 230 V supply for the unit must only be carried out by authorized personnel.
• The user is liable for ensuring that the above measures are taken.

Introduction
CAUTION
!
Under no circumstances should anyone attempt to service the microprocessor components or
Cab Command. Should a problem develop with the control system, contact your nearest Car-
rier Transicold dealer for replacement components.
The Control System consists of the microprocessor (
), Cab Command (
) and interconnecting wiring.
a. The Microprocessor includes the temperature control software and necessary input/output circuitry to inter-
face with the unit controls.
b. The Cab Command is remotely mounted in the truck. The Cab Command includes the LCD display and key-
pad. The keypad and display serve to provide user access and readouts of microprocessor information. The
information is accessed by keypad selections and viewed on the display.
