APPLICATION

The ML6984 and ML7984 are self-con tained, self-adjusting,

motorized valve actuators that mount directly onto V5011

two-way and V5013 three-way globe valves, providing linear

stem operation between 1/2 in. (13 mm) and 1 in. (25 mm).

ML6984 is for use with low voltage SPDT Series 20, Series

60 (on-off), or SP3T Series 60 (ﬂ oat ing) electro-me chan i cal

and elec tron ic controllers.

FEATURES

• Self-contained, motorized globe valve linkage.

• Microprocessor-based digital position sensing and

motor control for accurate positioning.

• Compact size for easy installation in conﬁ ned

spaces.

• NEMA 3R rain-proof cover for outdoor in stal la tion.

• Self-calibrating for valve stroke from 1/2 in. (13 mm)

to 1 in. (25 mm).

• DIP switch input conﬁ guration selection.

• LED (light-emitting diode) status indication.

• Conﬁ gurable to 3-wire mode for ﬂ oating models.

• 710 N 160 lbf (712 N) valve clos ing force.

• Usable with common transformer pow er supply for

mul ti ple ac tu a tors and con trol lers.

• 24 Vac or 28 Vdc power supply.

• Field-addable position feedback/auxiliary switch

mod ule avail a ble for 5-wire models.

ML7984 is for use with Series 70 0-10 Vdc, 2-10 Vdc,

4-20 mA; elec tron ic Series 90 “SuperMod”; and 135 ohm

modulating controllers.

ML6984, ML7984 SERIES 4000 DIRECT COUPLED VALVE ACTUATORS OPERATION NOTE: 1. Each time actuator terminals T5 and T6 are (re)powered, the microprocessor will cycle the valve through a full stroke to calibrate its position. Any stroke between 1/2 in. (13 mm) and 1 in. (25 mm) will be divided into 30 equal steps. Run time is proportional to stroke length and power supply voltage. The actuator will also slow down as the valve closes off the seat.

ML6984, ML7984 SERIES 4000 DIRECT COUPLED VALVE ACTUATORS See Fig. 19, if connecting TH5110D or TH6110D FocusPRO™ thermostats to ML6984. Conﬁgure the thermostats for Series 20 operation. ML6984 XL10 Controller Compatibility: XL10 controllers are designed to work with constant-speed actuators. ML6984 actuators use direct current motors which vary their speed as the valve seats or if power supply voltage is not consistent. ML6984 actuators in 5-wire mode offer 30 discrete positions only.

ML6984, ML7984 SERIES 4000 DIRECT COUPLED VALVE ACTUATORS NOTE: The 272630D position feedback/auxiliary switch module cannot be used with ML6984 3-wire installation. The 272630D requires continuous power. 5. To Replace ML6874: NOTE: 1. 1. 2. 6. The ML6984 is a direct replacement for the old ML6874 in single actuator hook-up. For parallel, multiple ML6874 actuators applications, an isolation relay must be used.
