The thermo contacts are fitted in series with the motor winding. They switch the motor off directly when a thermal overload occurs and they switch it on automatically after cooling down. 2 An extra motor protection unit is not required when using speed control units of the types ETH 32-, ETH 36-, and EPA 3-. These control units are already equipped with a motor protection unit. 5

Accessories ESM Motor protection unit for motors with fitted thermal control sensors (thermal contacts, PTC) Design Beautifully shaped plastic casing made of shock resistant polystyrol, protection class IP 54. All units are suitable for wall mounting and include: hand switches for frontal operation, operational signal lamp and control safety accessible from outside. Permissible ambient temperature: +4 C. Function Should the motor winding temperature rise excessively, the imbedded motor winding thermal contact or PTC will open the control circuit, causing the mains relay to drop out and thus disconnect the motor from the mains supply. The motor will also be turned off in the case of a mains-side dropout of the control phase, as well as if the contacts fail or if the mains supply is interrupted. The motor protection units are not equipped with an automatic re-poweron after a mains voltage failure and are thus fail-safe. After the motor windings have cooled down, a lock-out device in the relay circuit prevents the motor from switching itself on. The hand switch must first be momentarily turned to the -position and then back to the on position. The operational signal lamp indicates the operation of the motor. It goes out in the case of a malfunction. The motor protection units are suitable for group switching, i. e. several motors with the same switching can be connectedto a common switchingdevice. The sum of the motors rated power may not exceed the maximal device rated power. The thermal contacts of all motors are to be switched in series. The PTCs switched in series may not exceed the sum of 6.

Accessories ETH Speed setting transformatic, 5-step, with casing Design Completely plastic casing in protection class IP 54, Type: ETH 31, 35 and ETH 37-1/-2-8D. inted metal casing in protection class IP 23, Type: ETH 36 and ETH 37-4/-7-8D. All units are suitable for wall mounting and include: speed control via hand switch with -position and 5 switching steps, operating signal lamp, 23 V output for e. g. a solenoid valve. Permissible ambient temperature: -25 C up to +4 C. ETH 31 These units include no motor protection unit. Protection switches for thermal contact connections are to be laid in the conductor between the control device and the motor. In Nicotra Gebhardt externallymounted rotor motors, the thermal contacts are already bound into the motor winding. ETH 35, ETH 36, ETH 37 These units possess a motor protection installation for thermal contact or PTC connection with a supplementary warning signal lamp, a potential-free exchanger and a room thermostat connection (remote on off). Function For motors with built-in thermal contacts, these open the control current circuit when the permissible winding temperature is exceeded (ETH 31, 35, 36). Motors equipped with PTC thermistor give an electrical signal to the trigger unit (ETH 37) when the temperature exceeds the default value. The trigger controls the main relay thus cutting the motor feed. This causes the main fuse to fall out and disconnect the motor from the mains. After the motor winding has cooled down (ca. 2 Min.) or after remedying the cause of the malfunction, respectively, turn the main switch temporarily to the -position and then back to the operational position. 31

Description General The axial flow fan line is suitable for conveying air or other gases or vapours which are not particularly aggressive. The minimum temperature for the conveying media is -3 C and the upper temperature limit is given with the data of the technical specification of each type. Flow direction suction over motor flange. Horizontal or vertical installation is possible. Protection AQA 61, AWA 61 The axial flow fans are equipped with intake guard as a standard. Guards for discharge are available as an accessory ARA 61, ARA 62, These fans are made for being integrated in a duct system or for wall flush mounting and are not supplied with an intake guard. If there is by the way of installation or use the fan - no guard provided against a contact with the fan impeller the user has to ensure an appropriate protection according to DIN EN 294. Matching guards and automatic back draught dampers (discharge side) are available as an accessory. Accessories Every accessory has to be ordered separately. Specification, technical data and dimensions see chapter accessories. The selection of the matching control units is specified with the table Technical data Motoren The integrated motors are of protection class IP 44 or IP 54, - isolation class B, equipped with maintenance free deep grove ball bearings. They are selected for permanent operation S1 to VDE 53. In order to protect them against thermal overload they are provided with thermo contacts. The thermo contact either protect the motor by direct switch off because of being fitted in series with the motor winding, or in connection with a motor protection unit. So overload of the motor will be safely prevented. Please check wiring diagrams. All motors are 1% speed controlled. The speed variation is caused by a voltage variation and a subsequent change of the rotational slip. Elektrical wiring AWA 11 The fans of the line AWA 11- are supplied, as a standard, without terminal box. They are equipped with a free cable lead of about 45mm. The capacitor is supplied loose.
