Description and Utilization
Power element is basically made up of high power switching which is controlled by the Actuator output
or the Central Unit output. Actuator and Central Unit are parts of TERA program made by TESLA; see
–
contacts of actuator (central)
memory relay switch voltage on power relay coil. Power relay
is mostly located near an actuating unit (fan,
recuperation unit, etc.). By a switch on box of power relay it is possible to choose permanent switching of
relay
–
position ´ON´
or choose switching of relay by automatic control signal

TPS2 Power Relay can be used in this system:
TERA System for Radon Concentrations Regulating (Figure 1)
Regulating system diagram description
- Radon measuring probes located in building transmit their
current radon concentration values to central unit wirelessly. Central unit analyzes this information and on
the basis of measured (set) concentration level value it sends wireless command to actuator which is
hardwired with power relay. Power relay switches on a fan which decreases radon concentration within an
area. After decreasing of radon concentration, actuator receives a command to switch off the fan. This cycle
repeats depending on increasing or decreasing volume activity of radon in building.
