NoteThe following points must be taken into account with independent, external wiring:• All contact between the cables or wires that

are introduced and the heating element is to be avoided.

• Where necessary, use cables with sufficient numbers of wires, e.g. so that the heating and the actuator can be supplied separately with voltage.

Heating with the adjustable thermostat to preclude insufficient temperatures and the formation of condensation water in BELIMO NEMA 4X actuators with nominal voltage AC 24 V• Thermostat adjustable (+14 ... +122°F)• Utilization range -40°F to +122°F

ApplicationThe thermostat records the temperature in the actuator housing and switches the connect-ed heating system on when the temperature falls below the one that has been set. This prevents the formation of condensation on assemblies and electronic components, even in the presence of frequent and severe temperature fluctuations. The heating elements is designed for continuous operation.

Technical DataRange: +14...122°F (factory setting 86°F)Switching differential (temperature): 7 K (±4 K tolerance)Sensor element: Thermobimetal partsType of contact: NC contactContact junction resistance: <10 mΩ Service life: >100,000 cyclesConnection: 2-pole terminal, torque max. 0.5 Nm: Rigid wire line 2.5 mm2 Strand line with wire end ferrule 1.5 mm2Heating output: 20 WSwitch-on current: max. 6 ANominal voltage: AC/DC 24 V Heating element: Positive temperature coefficient resistor (PTC), self-regulating, temperature-limitingHeater: Aluminium profile, anodisedEMC: Accordance with EN 55014-1-2, EN 61000-3-2 and EN 61000-3-3Ambient temperature: -40 ...+122°FNon-operating temperature: -40 ...+158°F

Safety NotesIt is absolutely imperative that operators ensure that both, heating device and actuator, are disconnected from the volt-age source before settings or manipulations are carried out on the device.• The thermostat can be removed by trained personnel when repair work is being performed.• The heating device itself is not permitted to be removed. The entire actuator must be replaced when repair or warranty work is being performed!• The self-regulating function of the PTC heating element is not a substitute for the utilisation of the installed thermostat!• The thermostat is not permitted to be set at ≥ 90°F in the presence of ambient temperatures of ≤–4°F.• The following points must be taken into account with independent, external wiring: – All contact between the cables or wires that are introduced and the heating element is to be avoided. – Where necessary, use cables with sufficient numbers of wires, e.g. so that the heating and the actuator can be supplied separately with voltage (see «Electrical Installation»). – All legal regulations or regulations issued by authorities must be observed.• The thermostat is factory set 86°F. Set to your required setting.

Provide overload protection and disconnect as required.

Actuators may be connected in parallel if not mechanically mountedto the same shaft. Power consumption and input impedance mustbe observed.

3 Actuators may also be powered by 24 VDC.

Notes:

4Position feedback cannot be used with a Triac sink controller. The actuator internal common reference is not compatiable.

6Control signal may be pulsed from either the Hot (Source)or Common (Sink) 24 VAC line.

7 ZG-R01 may be used.

8Contact closures A & B also can be triacs. A & B shouldboth be closed for triac source and open for triac sink.

9For triac sink the common connection from the actuatormust be connected to the hot connection of the controller.

Mounting Installation Instructions ®

1. Turn the damper shaft until the blades are fully closed2. (1) Slip the actuator's universal clamp over the

damper shaft. Make sure that the duct and the con-trols on the cover are accessible. Place the actuator in the desired mounting position.

(2) Hand tighten the two nuts on the actuators univer-sal clamp.

3. (1) Disengage the actuator gear train by pressing the manual override button. Using a Phillips screwdriver press down and turn 90 degrees to lock the override. Rotate the clamp until centered.

(2) This can be done by inserting a screwdriver into the override component and manually moving the device clockwise or counter clockwise.

(3) Slide the anti-rotation bracket up under the actua-tor so it engages the actuator at the center of the cutout. Bend the bracket as needed to support the rear of the actuator. Secure to duct work with self-tapping screws (No. 8 recommended).

4. Loosen the nuts on the universal clamp. (1) Press the manual override button and rotate

clamp about 5° from the closed position (1/16" to 1/8" between stop and clamp).

(2) Tighten the two nuts on the universal clamp with a 10 mm wrench. Do not over tighten.

5. Remove cover by unscrewing the six screws. Make adjustments to the CW/CCW switch if needed. Adjust end-stops if required. Wire the actuator as described

on pages 4, 5 and 6. Insert position indicator flag in override component.

6. Install the cover. The damper is now fully closed but the actuator is 5° from fully closed. This is called "pre-loading" the actuator. When the actuator is powered and sent to the closed position, it will put its full torque on the shaft compressing the edge and blade seals. This ensures that the damper will meet its leakage rating. The actuator is electronically pro-tected from overload and will not be damaged.

Testing the installation without power1. Disengage the gear train with the manual override

button and move the shaft from closed to open to closed. Stroking the damper from fully open to close, with 5° of actuator stroke left, ensures there is no binding.

2. Correct any problems and reset.
