5.5

Generator D+

a)

Connection of the control unit and external
sensor according to the circuit diagram
“control units”
• rt

Power supply, plus – terminal 30

• ge

Switch-on signal – S+

• gr

Actual  temperature

•  wsrt Switch off burglar alarm system,

PIN 15, positive signal output for
relay, Imax = 200 mA
for ADR – feedback signal for timer

• br

Power supply, minus – terminal 31

• blws Diagnosis
• grrt

Nominal temperature

• brws Reference signal sensor

b)

Option
Activation of vehicle blower and / or
separate fresh air fan
The positive signal is only applied during the
“Low” control stage (PIN 16, positive signal
for relay, Imax = 200 mA)

c)

Wiring for operation to ADR / ADR99 (HGV
vehicle transporting dangerous goods,
e.g. tanker truck)

d)

When only one switching element is used for
item 5.2.1 and 5.2.2 it must be ensured that
on activating the function “open the battery
separating switch” (EMERGENCY OFF
function for ADR / ADR99 etc.), the switch
always separates immediately (regardless of
the heater status) and all the heater circuits
are disconnected from the battery.
