Rail heat control

mode

The rail heat can be controlled in several ways:

0: Rail heat is running all the time

1: Pulse control is used with a timer function follow-

ing the day/night operation

2: Pulse control is used with a dewpoint function. This

function requires that a signal is received about the

dewpoint value. The value is measured by a system

manager and sent to the controller via the data com-

munication.

0=ON, 1=Day/Night timer, 2=Dewpoint ctrl.

o85

o85 Railh. mode

Rail heat ON cycle

day

Rail heat power during day time. The ON period is set

as a percentage of the period

o41

o41 Railh.ONday%

Rail heat ON cycle

night

Rail heat power during night time. The ON period is

set as a percentage of the period time

o42

o42 Railh.ONngt%

Rail heat period

time

Period time for pulsing of rail heat

o43

o43 Railh.cycle

Rail heat PWM - Peri-

od time

Period time for the pulse width modulation

P82

P82 RailCyclePWM

Rail heat min. ON

cycle

Lowest permitted rail heat power. When the meas-

ured dewpoint is below the dened minimum limit

the rail heat will run with the set minimum power

o88

o88 Rail Min ON%

Dewpoint min. limit

If the measuered dewpoint is below the set value the

rail heat is running at minimum heat

o86

o86 DewP Min lim

Dewpoint max. limit

If the measured dewpoint is above the set value the

rail heat is maximum

o87

o87 DewP Max lim
