Programming the additional switch output (ST 632 only)

7.1.

General description (ST 632 only)

The ST 632 control unit has 2 additional switch outputs that can be configured and activated in a firing program.
⇒
The switch output on the controller can control an automatic exhaust air flap, an automatic intake air flap
or an automatic cooling system using a fan on the kiln separately or simultaneously.
⇒ Each switch output can switch a maximum of 250-300 mA at 230 V.
⇒ A relay must be used at these outputs to switch loads.
7.2.

Parameters for switch outputs (ST 632 only)

The additional switch outputs can be set in the parameter configuration (see section 12. / parameter no. 45 / 49).
Additional switch output
Switch output 1
Switch output 2
7.3.

Assignment of the switch outputs (ST 632 only)

Switch output 1/2 (Event 1/2):
⇒ With this setting, the switch output is controlled in such a way that its status changes at the beginning of a
ramp (heating and cooling ramps) or soak period.
⇒ Events are possible with a ramp as well as a soak period.
⇒ Examples for assignment:
• The kiln has an automatic air damper that should close at the beginning of a ramp (heating or cooling
ramp) or soak period and should open again at the end of a ramp (heating or cooling ramp) or soak
period.
• The kiln has an automatic cooling system using a fan and this should be switched on at the beginning
of a cooling ramp and should be switched off at the end of the cooling ramp.
Remark:
The kiln must be prepared at the factory for the use of a cooling system with a blower or fan.
Retrofitting a cooling system with a blower or fan in a kiln without a cooling system is generally
not recommended. Kilns with a cooling system are specially prepared and manufactured by the
manufacturer for use with a cooling system.
7.4.

Program switch outputs (ST 632 only)

When programming a ramp or a soak period – while programming a firing program – the switch output can also be
selected for the respective program step by pressing the switch output (event) key. Events are possible with a ramp as
well as a soak period.
