Pressure-controlled regulation of EXHAUSTO CDT chimney fan 2. 1 Use Area of use ·The EBC20 is designed for use with boiler systems with 1- and 2-stage burners. ·The EBC20 can also be used for boiler systems with modulating burners. ·The control system is intended for: > solid fuel boilers > atmospheric gas boilers > forced draft boilers for oil and gas > condensing boilers ·The EBC20 can control a chimney fan directly or indirectly via a frequency converter. 2. 2 Method of operation General function ·The control system monitors chimney draft and disconnects the burner in the event of errors (the alarmdiode on the EBC20 will turn on). ·When the boiler thermostat demands heat, the chimney fan will start at max. ·WhentheEBC20registerssufficientchimneydraft, theburnerisreleased. ·The EBC20 maintains the set pressure by regulating the voltage. ·Intheeventofaninsufficientpressuretheburnerwillbedisconnectedafter15seconds. "Insufficientpressure"islessthan64%ofthesetvalue, correspondingless than80%flow. ·When the boiler switches off, the chimney fan is also stopped. However, it is possible to set a post-purge period for the chimney fan (see page 22). Alternatively, the control system can be set up to keep the chimney fan running continuously (see page 21). Light emitting diodes and output signals All inputs and outputs are linked to light emitting diodes for the monitoring and service of the system (1. 4. 2 Light emitting diodes and terminal board, page 8 ). The EBC20 has 0­10V output signals for controlling multiple chimney fans via frequency converters or motor power relays. 2. 3 Electrical connection Thisworkmustbeperformedbyaqualifiedelectricalengineer, inaccordancewith locally applicable rules and legislation. ! Isolation switch The installation of the supply cable must be carried out in accordance with applicable regulations and legislation. When connecting pressure transducer (XTP) and frequency converter, shielded cable must be used. EXHAUSTO CDT stresses that according to EU's Machinery Directive an isolation switch mustbesetupinthefixedinstallation.
