TD 76

PROGRAM AND ELECTRICAL FEATURES TD 76 A

General design

TD 76 A  has thermostat-controlled automatic programs to 47° C or 60° C and time
programs up to 60 min.

Alternative connections
Alternative connections are single-phase, 230 V, 10 or 16 A with 1900 and 2850 W
power respectively, 2-phase 400 V, 10 A, 2850 W (normal on delivery) 3-phase, 400
V, 10 A, 2850 W or 3-phase, 230 V, 16 A, 2850 W heating capacity.

Switching

Switching between the various alternative connections is made directly on the con-
nection terminal board according to directions given.

Programs TD 76A

The program is a time program with marking every 20 minutes. The drying is
terminated by a cool-down period of 12 minutes. You can set this sequence directly
and to get an airing program.

The program unit

The program unit has a mecanically marked setting points, motor with 4-min-stages
and built-in buzzer.

Pushbuttons

The pushbuttons have the following functions:

S

Start of program by means of starter relay

T

Gives 47°C in pressed-in position and 70°C in released position

Thermostats

There are four thermostats : The first is of 47°C and the second of 70°C, are fitted to
the fan casing.
The third of 115°C (resets automatically) operates at 115°C switching out one of the
heaters if the temperature rises excessively. The fourth thermostat, also fitted to the
heater casing, operates at 150°C and provides protection against dangerous over-
heating. It must be manually reset.

The manual overheating protection breaks the contact to the starter relay, which
means that the machine stops completely when there is overheating.
