Actuator for modulating control AME 85QM

Description AME 85QM actuator is used together with large

pressure independent balancing and control valves type AB-QM DN 200 and DN 250.

Special features:

• position indication

• automatic adaptation of stroke to the valve’s end position to reduce commissioning time (self stroking)

• advanced design incorporates load related

“switch oﬀ” to ensure that actuators and valves are not exposed to overload

• manual operation

Installation Mechanical

Installation of the valve with the actuator is allowed in horizontal position or upwards. Installation downwards is not allowed.

Use the 57 mm castellated nut (supplied) to

ﬁt the actuator to the valve body. While the

actuator is being tted, a 8 mm Allan key can be

used to tighten the pinch screw in the valve body ring to stop the valve turning.

Allow for necessary clearance for maintenance

purposes.

Electrical

Electrical connections can be accessed by

removing the actuator cover. Two cable gland entries with thread (M20 x 1.5 and M16 x 1.5) are

prepared for cable glands.

Note: Cable and cable gland used must not compromise the actuator’s IP rating, and must ensure the connectors are fully strain relieved. Please observe local rules and regulations as well.

Wiring

24 Vac only.

Wiring for modulating control Wiring for 3-point control

Note: If switch SW6 is set to ON than use this wiring.

Automatic self stroking feature

When power is ﬁrst applied, the actuator will

automatically adjust to the length of the valve stroke. Subsequently, the self stroking feature

can be re-initialised by changing position of SW9.

Diagnostic LED

The red diagnostic LED is located on the pcb under the cover. It provides indication of

three operational states: Actuator Healthy (Permanently ON), Self Stroking (Flashes once per second), Error (Flashes 3 times per second - seek technical assistance).

DIP switch setting

The actuator has a function selection DIP switch

under the removable cover. In particular, if SW6 is set to ON, the actuator will perform as 3-point actuator. The switch provides the following functions:

• SW1: U/I - Input signal type selector:

If set to OFF position, voltage input is selected. If

set to ON position, current input is selected.

• SW2: 0/2 - Input signal range selector:

If set to OFF position, the input signal is in the range from 2 V to 10 V (voltage input) or from 4 mA to 20 mA (current input). If set to ON position, the input signal is in the range from 0 V to 10 V (voltage input) or from 0 mA to 20 mA (current input).

• SW3: D/I - Direct or inverse acting selector:

If set to OFF position, stem retracts as voltage increases. If set to ON position, stem extends as

voltage increases.

• SW4: —/Seq - Normal or sequential mode selector:

If set to OFF position, the actuator is working in range 0(2)..10V or 0(4)..20mA. If set to ON position, the actuator is working in sequential range; 0(2)..5 (6)V or (0(4)..10 (12)mA) or (5(6)..10V)or (10(12)..20mA).

• SW5: 0..5V/5...10V - Input signal range in

sequential mode:

If set to OFF position, the actuator is working in sequential range 0(2)..5 (6)V or 0(4)..10 (12)mA. If set to ON position, the actuator is working in sequential range; 5(6)..10V or 10(12)..20mA.

•

SW6: Prop./3-pnt - Modulating or 3-point

mode selector:

If set to OFF position, the actuator is working normally according to control signal. If set to ON position, the actuator is working as 3-point

actuator.

For this operation please refer to page 2 (wiring for 3-point control).

When DIP switch SW6 is set to ON than all

functions from other DIP switches become

inactive.

• SW7: LOG/LIN - Equal percentage or linear

ow through valve selector1:

If set to OFF position, the ow through valve is equal percentage. If set to ON position, the ow through valve is linear according to control

signal.

• SW8: 100% KVS/Reduced KVS

To be set to OFF position.

• SW9: Reset:

Changing this switch position will cause the

actuator to go through a self stroking cycle.
