WIRING FOR CONTROL AND FAN SUPPLY
Control
The DC logic signal can be provided by Eurotherm 2000 series temperature controllers for
example configured for DC logic outputs (see Figure 3-5).
Control by AC voltage is accomplished by contacts (or triac) provided by temperature or other
AC logic output controllers.
These contacts (or triac) apply the AC voltage specified in the product code (24 - 48 Vac or
100 - 230 Vac) to the TE200S input configured for this voltage.
Warning!
A 0.5A protective fuse must be installed in each feed wire connected to a supply
phase.
Contact (or triac) protection
The contacts (or triac) must be protected against overvoltages at the moment of opening by an
RC circuit (snubber), often integrated into temperature controllers (see Figure 3-6).
Maximum value of capacitor in the protective RC circuit:
22nF for 100 - 230 Vac (50 Hz and 60Hz ±2Hz);
47nF for 24 - 48 Vac (50 Hz and 60Hz ±2Hz).
Warning!
Increasing this value can lead to permanent conduction of the TE 200S.
Fan (63A rated unit)
The value of the fan supply voltage (115 Vac or 230 Vac) for fan-cooled units is specified in
the SSR product code.
Warning!
The fan connection must have a 0.5A protective fuse installed in each feed wire
connected to a supply phase.
