Page 7: Description
Description The PTR 225 N and PTR 237 N PENNINGVAC series vacuum transmitters offer a wide measuring range from 1×10 to 5×10 mbar and are based on measurement of cold cathode ionization current. Transmitter versions with an RS232 digital communication interface (P/N: 89642V02) and EtherCAT digital communication interface (P/N: 230703V02) can set up transmitter parameters and provide real time pressure measurement. -

- Corrosive or explosive gases - Direct sunlight or other heat sources Explosive Environments The PTR 225 N and PTR 237 N PENNINGVAC transmitters should not be used in explosive environments, due to their high voltage potential that can cause ignition. Bake out... -
Page 13: Vacuum Connections
Contamination Locate and orient the PTR 225 N and PTR 237 N PENNINGVAC where contamination is least likely. Vacuum connections The transmitters are available with different types of vacuum fittings. When mounting the transmitters, always ensure that all vacuum sealing items and surfaces are clean, without damage and free of particles. Do not touch the vacuum flange sealing surface. -
Page 14: Transmitter Installation (Electrical)
Transmitter Installation (Electrical) The PTR 225 N and PTR 237 N PENNINGVAC are available with different input/output connectors. Use a cable with strain relief to ensure proper electrical connection and to reduce stress on the connectors. Attention Ensure a low impedance electrical connection between the transmitter body and the grounded vacuum system to shield the sensor from external electromagnetic sources. -
Page 15: Switching On The High Voltage
a voltage greater than 4 V is present with reference to Pin 4. Operation of the PTR 225 N or PTR 237 N in the pressure range above 10 mbar will cause the accumulation of contaminations and will thus reduce service life. For this reason, the high voltage should only be switched on or off... -

Page 18: 4.4 Setpoint Relays
4.4 Setpoint relays The PTR 225 N and PTR 237 N PENNINGVAC have up to 3 mechanical relays that can be used for controlling external process equipment. The relay has closing and breaking contacts and the contacts are rated 30 VDC, 1A resistive load. -
Page 19: Operations
Operations Pressure output The PTR 225 N and PTR 237 N PENNINGVAC transmitters can provide pressure measurement output as an analog voltage or RS232 digital value (P/N: 89642V02) or EtherCAT digital value (P/N: 230703V02). For details about the digital interface, please refer to the Communication Protocol 300544663 (RS232) and 300544664 (EtherCAT). -
Page 20: 5.2 Analog Output
5.2 Analog output The PTR 225 N and PTR 237 N PENNINGVAC transmitters provide a voltage output as function of pressure. The standard output is 1.33 VDC/decade but can also be configured to emulate other analog outputs. Conversion formulae: ((Vout – 12.66)/1.33) -
Page 21: Cold Cathode Ignition
Analog output setup The PTR 225 N and PTR 237 N PENNINGVAC can emulate analog voltage outputs from other vacuum transmitters (Only for transmitters with a serial interface). Refer to the Communication Protocol 300544663 (RS232) and 300544664 (EtherCAT) for analog output setup. The analog output provides 16 bit resolution. -

Page 24: Faq (Frequently Asked Questions)
Digital output Q: How fast can I request pressure measurements via the digital interface? A: 10 times per second is the fastest recommended pressure request frequency. 300544652_002_C1 - 11/2016 - © Leybold... - Page 25 Q: Reverse voltage has been connected to power supply input. Is the transmitter damaged? A: Not likely – the transmitter power supply circuit has reverse voltage and over voltage protection, however, Leybold cannot guarantee that the transmitter will not be damaged. Q: The status LED is constantly illuminating red? A: The LED will turn red 5 min after the cold cathode has been started but was not successfully ignited.

Check electrical connections. Status LED illuminating red The LED will turn red 5 min after the cold cathode has been started but was not successfully ignited. Increase the pressure and/or clean or replace replaceable parts. 300544652_002_C1 - 11/2016 - © Leybold... -
Page 27: Maintenance
Contaminated parts can be cleaned by mechanical polishing or ultrasonic cleaned followed by alcohol degreasing (e.g. Isopropanol). Make sure that all parts are clean and remove any discoloring of the stainless steel and titanium parts. Alternatively the anode module or screens can be replaced with new parts. 300544652_002_C1 - 11/2016 - © Leybold... -
Page 28: Declaration Of Contamination
All dispatch instructions laid down in the manual must be followed e.g.: • Drain all service fluids • Remove filter elements • Seal all openings airtight • Pack / handle appropriately • Attach the declaration of contamination outside of the packaging 300544652_002_C1 - 11/2016 - © Leybold... - Page 29 300544652_002_C1 - 11/2016 - © Leybold...
