For proper and safe operation, the measuring device must be installed, operated, and serviced
according to NEC, local regulations, and these instructions. Otherwise, personal injuries or damage
or both can occur.
Only qualified persons should work on these devices.
1. Use within the conditions specified in the Swagelok General Industrial Transducer catalog.
2. Always disconnect the device from its power supply before opening it. Do not touch any of the
device’s contacts after installing.
3. The shield / ground connection must be wired to ground to protect the instrument from
electromagnetic disturbances.
4. If the device is visibly damaged or has been stored under inappropriate conditions,
turn off the device and do not use again.

1. Safety Regulations

2. Introduction
The Swagelok®PTI-PM remote panel mount display is a microprocessor-controlled device that supports one
universal interface for the connection of standard transducer signals (0 to 20 mA, 4 to 20 mA, 0 to 50 mV,
0 to 1 V, and 0 to 10 V) and frequency (TTL and switching contact).
The device features two switching outputs, which can be configured as 2-point controller, 3-point controller,
2-point controller with min-/ max-alarm or common / individual min-/ max-alarm.
2.1 Accessing the programming buttons
Before the PTI-PM can be used, it has to be configured for the application.
The device has three buttons that will be used during the configuration process.
■Left button (Button 1) is used to confirm your entry
■Center button (Button 2) is used to increase a value
■Right button (Button 1) is used to decrease a value
Note: Buttons 2 and 3 will increase or decrease in value by one each time the button is touched.
If the button is held down, the value will increase or decrease quickly.

Rev 0 6-04-WEL
To configure the PTI-PM, follow these steps:
1. Connect device to power supply.
2. Remove red front panel to access programming buttons.
3. Turn on power supply. The device will run its built-in test.
4. Enter the required input signals. (See section 4.)
5. Enter the required output signals. (See section 4.)
6. Turn off power supply.
7. Replace red front panel.
8. Connect device to electrical connection. (See section 3.)
There are two indicator lights to the far left and right of the three buttons.
■Left indicator light displays the status of the first output
■Right indicator light displays the status of the second output
Button 1 Button 2 Button 3
First output status Second output status
Note: In order to avoid undefined input states and unwanted or wrong processes, we
suggest connecting the device’s switching outputs after the device has been configured
properly.

3.4. Connecting switching outputs
The device features two switching outputs. There are three different operating modes for each switching output.
The operating modes are:
Low-Side: “GND-switching”NPN output (open-collector)
The switching output is connected to the negative rail of the supply voltage
(connection 3 or 5) when active (switching output on).
High-Side: “+Ub-switching”PNP output (open-collector)
The switching output is connected to the positive rail of the supply voltage
(connection 4) when active (switching output on).
Push-Pull: The switching output is connected to the negative rail of the supply voltage
(connection 3 or 5) when inactive. When the switching output is active, it is
connected to the positive rail of the supply voltage (connection 4).
If one output is an alarm output, the output will be active in idle state (no alarm present). The output transistor opens or
the push-pull output changes from +Uv to –Uv when an alarm condition occurs.
Note: In order to avoid unwanted or wrong switching processes, connect the device’s switching outputs after you have configured the
device’s switching outputs properly.

(without individual supply voltage)
3.4.2. Connection with configured high-side
switching output (PNP output, switching to +Uv)
Connecting consumer loads (relay and lamp)
(with individual supply voltage)
Do not not exceed the limits of the voltage and switching outputs.

3.4.3. Connection with configured push-pull switching
output
Note:
Connections 3 and 5 are electrically connected internally.
When switching higher currents (greater than 50 mA),
the –Uv connection should not be attached to the device
(connection 3) but to the –Uv connection of the external
voltage supply to eliminate ground displacement.

4. Configuring the Device
Note: If you do not press any button for more than 60 seconds, the configuration of the device will stop.
The changes you have made will not be saved.
Note: Buttons 2 and 3 feature a “roll-function.” Pressing button 2 once raises the value by one; pressing button 3 once lowers the
value by one. Pressing the button for longer than 1 second increases the counting speed. The device also features an
“overflow-function;” when reaching the upper limit of the range, the device switches to the lower limit, and vice versa.

Note: When changing the measuring mode “InP,” the input signal “SEnS,” and the measuring unit “Unit,“ all settings will be
changed to factory default. You have to set all the other settings, including the settings for zero and span adjustment
and switching points.
4.1. Selecting an input signal type
■Turn the device on and wait until it completes its built-in segment test.
■Press button 2 for longer than 2 seconds. The device displays “InP”('INPUT').
■Use button 2 or button 3 to select the input signal (see table below).
■Confirm the selection with button 1. The display will show “InP”again.
Depending on the selected input signal, additional configurations will be needed.
3.5. Wiring of multiple PTI-PM digital indicators
Inputs and outputs are not electrically isolated. When interconnecting several PTI-PM, make sure there is no
potential displacement.
Make sure to observe the following point:
■When several PTI-PMs are connected to the same power supply unit, electrically isolate the transducers.
