Safety Notes

To avoid personal injury and damage to devices, it is absolutely essential for these instructions and safety notes to be read carefully and reviewed prior to assembly and use.
Do not dismantle actuator with the safety spring function! There is risk of injury and death in the event of improper handling!
The actuator is heavy. Handle with care to avoid injury or product damage.

Wiring

Do not touch anything on the PCB!
Do not remove the service cover before the power supply is fully switched off.

Electrical connection ❶

iSET actuator mounting to pressure actuator ❷
Stand-By mode for manual operation and differential pressure setting ❸
Set-point range see rating plate on the pressure actuator*

1. Start-up of system *
2. Set flow rate on a motorized valve over which the differential pressure is controlled, to about 50 % *
3. Adjustment
   • Observe pressure indica tors *
   Enter the Stand-By mode for manual operation
   • Pushing the button on the actuator increases the set-point (squeezing the spring)
   • Pushing the button redu ces the set-point (stretching the spring)

End switch setting for MIN/MAX set Δp ❹
Slider ① can be set to limit min. ∆p
Slider ② can be set to limit max. ∆p
Fix the sliders ①, ② with 2 srews ③
Slider ② may be sealed ④

• see instruction for relevant combination pressure actuator/ valve
  DIP switch setting ❺

S1/DIP 1
Input signal type selector:
OFF: Input signal Y is set to voltage (V)
ON: Input signal Y is set to current (mA)
S1/DIP 2
Output signal type selector:
OFF: Output signal X is set to voltage (V)
ON: Output signal X is set to current (mA)
S1/DIP 3
Direct or inverse acting selector (Fig. 2):
OFF: Actuator is direct acting to input signal
ON: Not to be used for iSET
S1/DIP 4
Normal or sequential mode selector:
OFF: Actuator is working in range 0(2)-10 V or 0(4)-20 mA
ON: Actuator is working in sequential range; 0-5 V or (0-10 mA) or (5-10 V) or (10-20 mA)
Signal range selector S1/DIP 6 sets the sequential range.
S1/DIP 5
0-10 V/2-10 V – Input/output
OFF: 0-10 V; input signal is in the range from 0-10 V (voltage input) or from 0-20 mA (current input)
ON: 2 –10 V; input signal is in the range from 2-10 V (voltage input) or from 4-20 mA (current input)
Signal range selector S1/DIP 1 & DIP 2 sets Y and X signal.
S1/DIP 6
Sequential range selector:
OFF: 0-5 V or (0-10 mA)
ON: 5-10 V or (10-20 mA)
[S1/DIP 4 = ON!] S1/DIP 7
OFF: iSET
ON: iNET
S1/DIP 8
Not used
See AMEi 6 iNET data sheet

S2/DIP 1
OFF: analog MCV control signal
ON: 3-point MCV control signal
S2/DIP 2
OFF: analog MCV control signal
ON: 3-point MCV control signal
S2/DIP 3
Not used
**S2/DIP 4**
OFF: Analog signal (V/mA)
Actuator operates in analog mode
ON: MOD BUS
Actuator operates in digital mode
In analog mode S2/DIP 4 = OFF, DIP switches S1/DIP 1-7 work as active functions.
In digital mode S2/DIP 4 = ON , DIP switches S1/DIP 1-7 work as a digital addresses.
In digital mode Modbus RS485 could be used either for the monitoring purposes or for the AMEi 6 actuator positioning.

Calibration ❻
Calibration to the desired pressure actuator stroke (min-max spring setting).
Before calibration drive the actuator out of end positions (minimal gap between sliders ①,② and pin on the end switch ③ has to be ensured).
To start calibration procedure, press and hold RESET button for 5 seconds until the green light starts flashing. End positions of the actuator are automatically adopted based on pre-set end switch positions sliders ①,②. Actuator goes to the stationary mode and starts responding to the control signal. Depends on min-max Δp setting (position of sliders ① and ②), calibration may take up to ~1 h (in case of max available Δp range-stroke is set).
Calibration procedure need to be repeated every time when min/max spring setting is changed (position of sliders ① and ② is changed).
