Honeywell Relay CM 32 PR TW30/TS5

MICROFLA T SERIES APPLICATION TYPES CM32PR CE32PR This range of electronic gas burner control systems has been specifically designed for atmospheric pre-mixed gas burners for intermittent operation (systems for non­ AUTOMATIC CONTROL SYSTEMS WITH permanent operation). MANUAL AND ELECTRIC RESET FOR The control unit type CM32PR is provided with non-volatile PRE-MIXED GAS BURNERS AND lockout, i.e. the restart from the safety shutdown condition can only be accomplished by a manual reset of the system. INSTALLATIONS (PROVIDED WITH FREE The control unit type CE32PR is provided with volatile TERMINALS FOR AN EXTERNAL lockout, i.e. a restart from the lockout condition can be IGNITION DEVICE) accomplished by an interruption of the mains power supply and its subsequent restoration or by means of the heat demand to the control. The automatic burner control units of this series are suitable for: - combi boilers (only type CM32PR); - heating boilers (only type CM32PR); - water heaters. These controls are provided with free terminais for an external ignition device (selected the appliance manufacturer). As a result, these controls can be used for applications where ignition is particularly difficult, thus avoiding the use of pilot valves and hot surface ignitors. To reduce the electromagnetic interference produced by ignition devices, these control units can be fitted with our electronic ignition transformers type TC1AF-TC2AF with inbuilt E.M.C. filter (see technical sheets about "Electronic ignition transformers"). FEATURES TABLE 1 shows the main features of this series. Other important features are: - EC certification type (CE Reg. N ° 63AT1990) in accordance with the European Gas Directive Appliance 90/396/EEC amended by 93/68/EEC; in compliance with EN 298 (European standard for automatic gas burner control systems and flame detectors for gas burners); output for the control of the ignition device by means of supply voltage; possibility of mounting a resistor (0 + 220 ohm) in series to the valve outputs, in case the valves operate with direct current obtained through the rectification of the supply alternate current by means of one or more diodes; - for non-volatile lockout versions, possibility of mounting a resistor (0 + 470 Kohm) in series to the lockout signal output, to avoid possible damages to the control in case the connections of the reset push-button and the connections of the lockout signal are reversed; - two independent safety contacts in series on the gas valve output; - flame monitoring by the rectification property of the flame (ionization). · . r _ . ·--:- .· -- . .- - 7�- - .. • _ � ��6'"' .. . .-:. . ·� ."· . . -. .. - :.\c�-- . -. - .·
