SIEMIENS SIPART PS2 (6DR5...) Electrical Positioner Operation Guide

Vibration/acceleration environment treatment

The equipment is equipped with a friction clutch and a gear lock with a transmission ratio selector to cope with strong vibrations/accelerations (such as emergency shut-off valves, steam shock scenarios)

Locking steps: Ensure that the gear lock is in the neutral position → Confirm the gear ratio selector (33 ° or 90 °) → Lock the gear lock with a 4mm screwdriver → Secure the friction clutch (non explosion proof shell version), ensuring that the gear ratio selector is set to the same position as the gear lock (to avoid position detection delay)

Optional module installation

Optional modules for standard/intrinsic safety versions: position feedback module, alarm module, SIA module, mechanical limit switch module, EMC filtering module, NCS sensor, internal NCS module

Optional modules for explosion-proof shell version: only supports position feedback module, alarm module, and internal NCS module; The internal NCS module is used for wear free position detection and is installed in the same slot as the position feedback module

Connection (electrical and pneumatic)

electrical connection

Basic requirement: When the environmental temperature difference exceeds 20 ° C, it should be left to stand for several hours before being powered on (to avoid condensation); When the ambient temperature is ≥ 60 ° C, cables with a temperature resistance of ≥ 80 ° C must be used; The 2-wire version prohibits connecting the voltage source to the current input terminal (I2w, terminals 6/7) and requires the use of a high impedance power supply

Wiring for different communication versions:

With/without HART: Supports 2/3/4 wire system, 2-wire current input 4-20mA (terminals 6+, 7-)

PROFIBUS PA: Bus circuit connection terminals 6/7, equipped with safety shutdown input (terminals 81+, 82-)

FOUNDATION Fieldbus: Bus circuit connection terminals 6/7, supporting simulation enable function

M12 connector adaptation: The M12 pins of different modules correspond to different functions, such as the 61+pin 1 (brown) and 62- pin 3 (blue) of the position feedback module 6DR4004-6J/8J

Pneumatic connection

Interface specifications: All are G ¼ or ¼ "NPT internal threads, Y1 is the driving pressure for single/double acting actuators 1, Y2 is the driving pressure for double acting actuators 2

Interface positions for different models:

6DR5. 0/1/2/3: The pneumatic interface is located on the right side of the locator, including Y1, Y2, air source PZ, and exhaust port with muffler

6DR5. 5/6 (Explosion proof enclosure): The pneumatic interface is on the right side, including Y1/Y2 flow restrictor, enclosure ventilation port, and exhaust port

Safe location settings:

When power is off: single acting actuator Y1 releases pressure; Double acting actuator Y1 applies pressure (maximum driving pressure) and Y2 releases pressure; Fail in Place actuator maintains the current pressure of Y1/Y2

Usage of flow restrictor: When the actuator travel time T>1.5s, rotate the Y1/Y2 flow restrictor clockwise to reduce the air output. It is recommended to close it first and then slowly open it. The double acting valve should ensure that the two flow restrictors are set close to each other

Debugging (Commissioning)

Basic safety precautions

Installation and connection must be completed before debugging in hazardous areas, and equipment must be turned off (except for Ex i version); If there may be water in the compressed air pipeline, the purge air selector should be set to "OUT" (then set to "IN" after drainage)

Special requirements for natural gas operation: Only intrinsically safe (Ex ia) equipment can be used; Prohibited from operating in enclosed spaces; Adequate ventilation is required (see technical data for maximum ventilation capacity); Prohibit the use of mechanical limit switch modules; Relieve pressure for at least 2 minutes before maintenance

Initialization type and process

Initialization type:

Automatic initialization: Automatically detect the direction of action, actuator stroke/rotation angle, stroke time, and adapt control parameters, with a time consumption of ≤ 15 minutes

Manual initialization: manually set stroke/rotation angle, and automatically detect other parameters (applicable to PTFE lined valves)

Data replication: Copy the initialization data of the original device when replacing it to avoid process interruption

Core parameters (1-5):

Parameter function applicable to actuators, optional parameter value units

1. YFCT action direction/detection type linear/angular stroke linear: WAY/- WAY/FWAY/- FWAY/LWAY; Angular travel: turn/- turn; NCS adaptation: ncSt/ncSL/ncSLL, etc-

2. YAGL locator shaft rated rotation angle stroke 33, 90 degrees

3. YWAY travel range (optional) Linear (WAY/- WAY/ncSLL/- ncLL) OFF, 5, 10, 15, 20 (33 ° short lever); 25, 30, 35 (90 ° short leverage); 40~130 (90 ° long lever) mm

4. InitiatA automatically initializes all NOINI (uninitialized) and Strt (start)-

5. InitiatM manually initializes all NOINI (uninitialized) and Strt (start)-

Automatic initialization steps for linear actuators:

Press and hold the button for 5 seconds to enter configuration mode → Call 2. YAGL to confirm consistency with the transmission ratio selector → Set 3. YWAY (optional) → Call 4. InitiatA and press and hold for 5 seconds to start → Display "FINSH" after completion
