Failure to follow them could damage the product or cause a hazardous condition.. heck ratings given in instructions and on the product to ensure the product is suitable for your application.. The installer must be a trained, experienced service technician.. After installation is complete, check out product operation as provided in these instructions.. DO NOT electrically operate the actuator before assembly to the valve because damage not apparent to the installer may occur. IMPOTANT efore installing the valve, raise and lower the valve stem to make sure that the valve stem operates freely. Impaired stem operation can indicate that the stem was bent by rough handling. This condition can require repair or replacement of the valve. Protect the stem from damage due to bending or scratching. Damage to the stem packing may result. Proper Use Valves are to be installed by skilled personnel and in strict accordance with installation instructions and local regulations. Honeywell assumes no responsibility for damages or injuries resulting from non-compliance with installation instructions or standard good practice when mounting, operating, or maintaining the valves, even if not explicitly mentioned in the installation instructions. Observe all safety practices when working with steam systems. Mounting. Ensure that valve body is installed correctly, arrow pointing in the direction of flow.. Actuator can be mounted in any position; however, it is preferable that it is mounted above the horizontal plane of the pipe. This minimizes the risk of damage to the actuator in the event of condensation or valve gland leak. hen controlling steam, rotate the valve body with the actuator beside the valve to avoid exceeding ambient temperature limits of the actuator. For the same reason, do not mount ML Actuators to steam valves in enclosed cabinets. For on-off control of steam in small pipe sizes, Honeywell recommends V80J zone valves.

9 ML698, ML798 SEIES 000 DIET OUPLED VALVE ATUATOS OPEATION Each time actuator terminals and are (re)powered, the microprocessor will cycle the valve through a full stroke to calibrate its position. Any stroke between / in. ( mm) and in. ( mm) will be divided into 0 equal steps. un time is proportional to stroke length and power supply voltage. The actuator will also slow down as the valve closes off the seat. The LED lights when terminals and are powered, and flashes when the actuator is in motion. is connected to Terminal in ML698 and to Terminal in ML798. Initial calibration does not apply to ML698 installed for -wire control or installed for -wire control without the 760D position feedback/auxiliary switch module. Span and start positions will need to be set during controller setup. See ML698 Operation -wire, below. ML798 always conducts a self-calibration sequence when (re)powering up. ML798 Operation The microprocessor responds to the signal across the input terminals based on the configuration DIP switch settings. hen correctly connected to the actuator, a control signal between signal input terminals is converted to a digital run time and compared to pulse counts from the first gear in the gear train. hen these counters are equal, the drive motor and drive shaft are stationary. As long as the value of the controlled medium remains at the controller setpoint, the control loop circuit is in balance, and the actuator does not run. hen the controller set point or controlled temperature changes, the controller output voltage is changed, causing the counters to differ. As the actuator moves in the direction to correct the difference, the counters increment or decrement, and stop the actuator when the input and gear counts agree. At the end of the valve stroke, the actuator develops the necessary force for positive valve close-off. The motor stops automatically when the motor draws a predetermined current which corresponds to a force level. The digital counters are reset and calibrated at each end of stroke. Modulating actuators will automatically travel to the position corresponding to analog input signal following the self-calibration cycle. AUTION Disconnect power supply before beginning installation to prevent electrical shock and equipment damage. All wiring must comply with applicable local electrical codes, ordinances, and regulations. Make certain that the voltage and frequency of the power supply correspond to the rating of the device. DO NOT electrically operate the MLx98 actuator before assembly to the valve because damage not apparent to the installer may occur. DO NOT connect Vac between any ML798 signal input terminals. DEVIE FAILUE ILL ESULT.. The ML798 must be field configured with the DIP switches which are located beside the terminal block. See wiring diagrams for details. Turn power off before setting any DIP switches.. There is a. second delay in actuator response to every signal change. This occurs to screen out electrical noise.. For proper operation, voltage on the and must not be less than Vac or Vdc during running or force generating stages. Increase transformer VA rating or use a model with better regulation if voltage drops below Vac when the valve is closing off. ML698 Floating Operation, -ire The motor is controlled by a microprocessor. onnecting to for /0 second or longer tells the microprocessor to cause the actuator to drive upwards. onnecting to will cause the actuator to drive downwards. For floating control, the actuator will remain in the last position when there is no connection to. At the end of the valve stroke, the actuator will develop the necessary force for positive valve close-off. As forces are developed, the current to the motor increases. The microprocessor stops the actuator automatically when motor current and force reaches the factory-calibrated level. There must be at least. second delay between successive floating input signals. The actuator will ignore floating signals during calibration cycle and does not remember any pulses sent during this period. The controller may need to run through its own calibration cycle before use. ML698 Operation, -ire ML698 may be installed like a conventional (nonelectronic) floating actuator. The interface electronics are powered at the same time as the motor. Pulses must be at least 00 ms long with a delay of at least 00 ms between pulses. hen ML698 is not powered between terminals and /, self-calibration will not occur. The controller must drive the valve through a cycle manually to calibrate stroke to the controller

10 ML698, ML798 SEIES 000 DIET OUPLED VALVE ATUATOS The 760D position feedback/auxiliary switch module cannot be used with ML698 -wire installation. The 760D requires continuous power. ML698 XL0 ontroller ompatibility XL0 controllers are designed to work with constant-speed actuators. ML698 actuators use direct current motors which vary their speed as the valve seats or if power supply voltage is not consistent. ML698 actuators in -wire mode offer 0 discrete positions only. To minimize potential valve position drift, XL0 controllers should use the -wire installation and be programmed for a daily valve exercise cycle. ML698 On-Off Operation For on-off operation, ML698 requires a Vac SPDT contact. An interface relay such as A889 is required to power the anticipator heater of an electromechanical thermostat such as T87F (See Fig. 7).

11 ML698, ML798 SEIES 000 DIET OUPLED VALVE ATUATOS To eplace ML78 or ML98. The old ML78 or ML98 actuators cannot be used with new ML798 valve actuators in the same circuitry, unless the old models are each powered by their own transformer to prevent cross-talking.. The ML798 is a direct replacement for all old ML78 and ML98, except: a. hen replacing the old reverse acting models, the signal input wires to the new devices no longer need to be reversed. Just follow the terminal polarity designations and DIP switch settings. b. hen replacing the old actuator which has an Electronic Series 90 Supermod controller - e.g.: T77, 97, H77, or the old interface resistor must be removed. The ML798 Series 000 will work directly with the controller without the external 0 ohm resistor. c. hen replacing the old ML78 (ma model) in multiple-actuator installations, resistor(s) will be needed. Use esistor Kit (part no. 78) and set DIP switches accordingly. See Figures 7 and 8. To eplace ML68A. The new ML698 is a direct replacement for the old ML68A in single actuator or parallel multiple actuators hook-up. The old and new actuators can be mixed in the same electrical circuit. For multiple actuators controlled by a common controller in parallel, these actuators must be wired so that they all travel in the same direction.. hen replacing the ML68A009 (80 lbf) with this new ML698 on the V0 valve, the installed valve adaptor (part no. 769A) on the valve stem and actuator assembly is still needed. The 760D position feedback/auxiliary switch module cannot be used with ML698 -wire installation. The 760D requires continuous power. To eplace ML687. The ML698 is a direct replacement for the old ML687 in single actuator hook-up.. For parallel, multiple ML687 actuators applications, an isolation relay must be used. The isolation relay contacts should be placed in the new ML698 actuator signal input and circuit. To eplace Line Voltage Auxiliary Switches These accessories are no longer available. eplace the old actuator with new model and 760D position feedback/ auxiliary switch module. Operate an external relay, such as 88U, using the adjustable SPDT pilot duty output on the 760D. If a second, independent output switch is needed, wire the -0 Vdc position feedback signal to an Approved, adjustable, voltage-controlled relay. HEKOUT ML798.
