PRODUCT OVERVIEW Product Description Our Stuart Pulse Trade Circulators features a robust cast iron pump housing and is ideal for the transfer of liquid within systems for hot-water heating, air- conditioning and ventilation. This circulator features variable speed controls to constantly measure pressure and flow and adjust the speed according to the set operating mode.
SAFETY INSTRUCTIONS General These operating instructions are part of the product and contain basic information that must be observed during assembly, installation, operation and maintenance. For this reason it must be read by the installer and the responsible qualified personnel or the operator before performing assembly works.

delivery, the pump ist set to the AUTO Smart Adapt operating level. By repeatedly briefly pressing of the selection button, the operating modes: constant speed, constant pressure, proportional pressure and AUTO Smart Adapt are switched through continously. The selected operating mode is indicated by the corresponding LED with characteristic symbols.

PWM FUNCTION Optional special function PWM input This function allows the pump speed to be controlled by an external controller. To use this function, the pump must have the appropriate input. This external input can be recognized by an additional 3-pole connection cable to which a suitable external control can be connected.

Second side connected: • Must reliably prevent direct contact with the cable conductors when installed, i.e. the terminals must be touch-proof and the terminal connections must be protected against unintentional contact by a fixed cover. • Must meet the requirements of protection class I (connection to protective earthing).

The PWM control signal is a digital signal in which the rotational speed information is included in the pulse width. The control signal must meet the following requirements: Example of a PWM signal with a value of 40%: PWM % = 100 * t / T PWM % = 100 * 0.4 / 1 = 40 % For T, frequencies between 200 Hz and 4 kHz are acceptable.
Page 17
Heating characteristics P1 In the range from 0 to 10% of the PWM signal, the pump runs at maximum speed for safety reasons. (The prerequisite is that the pump is set to constant rotatioinal speed adjustment III when selecting the operating level (chapter 6.3)). In the event of a disturbance in the PWM adjustment or damage to the cable, this ensures that the heat generated by the heat generator is transferred.
Page 18
Solar characteristics P2 In the range from 0 to 5% of the PWM, the pump stops for safety reasons. If the PWM signal is switched off, e.g. due to a fault in the controller or an interruption in the signal cable, the pump stops. This is to prevent overheating of the solar system.

PWM feedback signal (power consumption) By means of a PWM feedback signal, it is possible to send information about the operating status of the pump to an external control. It contains information about the actual power consumption and errors of the pump. The output signal has a constant frequency of 75 Hz and is galvanically insulated from the rest of the pump electronics.
FILLING AND VENTING THE SYSTEM Fill and vent the system properly. To vent the pump, the electronics should be set to level III and operated in this position for at least 20 minutes. Caution After this procedure, you can set the pump to the desired control mode. Incomplete venting will result in increased noise during operation of the pump and the system.
ASSEMBLY Correct assembly position of the motor A voltage-free assembly must be carried out with the pump motor in a horizontal position (the direction arrow on the pump body indicates the flow direction). When carrying out the thermal insulation works, make sure that the pump motor and the electronics housing are not insulated.
ELECTRICAL CONNECTION Connect the mains cable to the pump as shown in the figure. Caution! Mains voltage! Always observe the necessary safety measures, VDE regulations and local regulations. The cross-section of the cable must not be smaller than 0.75 mm2. When using fine-wire cables, use wire-end ferrules.
MAINTENANCE AND SERVICE Before carrying out maintenance, cleaning and repair works, disconnect the system from the power supply and secure it against being switched on again by unauthorized persons. At high water temperatures and system pressures, wait for the pump to cool down beforehand. There is a danger of burns!
FAULTS, CAUSES AND REMEDIES Maintenance works or repair attempts may only be performed by qualified personnel. Before carrying out maintenance, cleaning and repair works, disconnect the system from the power supply and secure it against being switched on again by unauthorized persons. At high water temperatures and system pressures, wait for the pump to cool down beforehand.

Error pattern or Possible cause Remedy pump error code Rotor block Disconnect the pump from the power supply and secure it against being switched on again. If possible, close the shut-off valve upstream and downstream of the pump or drain the water. Depending on the operating state of the system, hot water may escape! There is danger of burns! Unscrew the motor head...
