They are suitable for use in conjunction with controls providing switched or floating single-pole, double-throw (SPDT) control outputs to operate Honeywell's standard valve series in heating, ventilation, and air conditioning (HVAC) applications. Safety Protection class, 24V models III according to EN60730-1 Protection class, 230V models I according to EN60730 Protection standard IP54 according to EN60529 Flame retardant housing V0 according to UL94, with metal cable gland Noise level Wiring Wiring terminals Cable entry Material Cover Yoke and base Weight Dimensions 45dB(A) 1. 5 mm M20x1. 5 and knock-out for PG11 ABS Aluminum diecast 2. 0 kg See Fig. [. . . ] The actuator stem is connected with the valve stem by a button keyed retainer connection. Via installed microswitches, the internal force sensor switches off the actuator precisely when the nominal stem force is reached. Auxiliary Potentiometer The auxiliary potentiometers (see Fig. They can be used as feedback potentiometer and/or to provide remote indication of the valve position. A cable gland PG11 is delivered with the unit. accessory-type auxiliary switches 250 Vac / 5 (3) A (package contains two SPDT switches) single auxiliary potentiometer (full range: 220 ; operating range: 135 ) single auxiliary potentiometer (10k ) stroke 20 mm 38 mm 20 mm 38 mm 20 mm 38 mm order no. 43191680-002 43191679-001 43191679-002 43191679-007 43191679-008 Manual Operation The actuators are equipped with a manual operator used in case of power failure. Manual operation is only allowable after the power supply is switched off or disconnected. To operate, push the manual operator knob down and turn counter-clockwise to move the stem downwards and clockwise to move the stem upwards. If the actuator returns to automatic control, the manual operator knob unlocks automatically. NOTE: Manual operation allows a very high closing force capable of jamming the actuator spindle and exceeding the rating of the force switches, so that the motor cannot move. Therefore, after a manually close-off operation, it is necessary to release the spindle one turn by turning the manual operator knob, so that the manual operator will automatically disengage on power resumption. High Temperature Kit Two options for applications with medium valve temperatures of +150. . . +220 °C are available for the following valves: order number High-Temperature Kit 43196000-001 valve V5011A/V5011K V5013A/V5013G V5011R/V5013R V5328A/V5329A V5011A V5013A/V5013G V5328A/V5329A V5049A V5050A V5328A V5016A V5025A V5049A (PN25/40) V5050 (PN16) V5050 (PN25/40) DN 15 ­ 40 15 ­ 40 15 ­ 50 15 ­ 32 50 50 40 ­ 80 15 ­ 65 15 ­ 80 100 ­ 150 100 ­ 150 100 ­ 150 80 ­ 100 100 ­ 150 100 Accessories The following accessories are available upon request: 43196000-002 Auxiliary Switches The actuators can be equipped on-site with an auxiliary switch unit having two switches (see Fig. Their switching points are adjustable over the full length of the actuator stroke.
