Kalmar’s ECS - Electronic Control System - is a modular control
and monitoring system to ensure optimum operational security
and total economy. It is possible to combine the system’s different
modules in a number of different ways.
All vital points of the trucks different systems are connected to
one or several central computer units, ECUs. A terminal display
in the operator’s cab shows current values and generates an
alarm if the values exceed the programmed tolerances.
DRD Container machines are equipped with ECS as standard.
Depending on how respective machines are equipped, one, two
or three ECU central units may be fitted.
ECU 1 is used for different additional modules, such as 01 Au-
tomatic Gear Changing, 04 Lever Steering, 06 Mini-steering, 07
Monitoring. See separate descriptions in respective sections.
ECU 2 is obligatory and is used to control the El-Servo cir-
cuits. See the El-Servo section. ECU 2 also functions as
overload protection and for the regeneration system.
ECU 3 is used for machines with modules according to the
table below.

Optional equipment
The ECS:
– monitors the engine and gearbox to ensure reasonable
operating conditions
– monitors the components in the system, e.g., sensors, to
ensure their correct function
– provides torque controlled automatic gear changing
– interrupts hydraulic functions when overload of the steer-
ing axle occurs
– controls the regeneration function for boom extension and
lift cylinders
– controls vertical lift, balance, pile slope etc.
If a fault occurs:
– a red warning lamp blinks on the terminal
– an error message appears on the terminal display
– The ECS limits the functions of the truck in different ways
depending on the seriousness of the fault. Certain func-
tions are monitored on two levels, where level 2 limits the
functions of the truck. See the error messages on the ter-
minal display on the following pages.
