1. APPLICATION
The PCE-P30U programmable transducer is designed to convert tem-
perature, resistance, direct voltage and direct current signals into
a standard DC voltage or DC current signal. The output signal is galva-
nically isolated from the input signal and power supply. The transducer
is tted with a 2x8 LCD screen.
Features of the PCE-P30U transducer:
•converting measured values into any output signal based
on an individual linear characteristic,
•calculating measured values using one of ve implemented
mathematical functions,
•calculating measured values based on a 21-point individual
characteristics,
• one or two NO (normaly open) relay alarms operating in 6 modes
•auxiliary power supply 24V DC 30mA switched on/o󰀨 by software
(options),
•indication of exceeding the alarm values set,
•programming alarm and analog outputs with a reaction to selected
input value (main input, auxiliary input or RTC),
•real time clock (RTC) with independent battery supply
•recording the input signals in programmed time periods in the inter-
nal memory and on an SD/SDHC card (option),
•internal archive memory with 534336 record capacity,
• automatic decimal point setting,
• preview of preset parameters,
• password protected parameter change
•RS-485 interface support with the MODBUS protocol in RTU mode,
• programmable averaging time,
•Median lter with various number of samples
•SD/SDHC memory cards support – compatible with FAT and FAT32
le system (option),
•RS-485 interface Master mode – ability to poll a single slave device

7
•RS-485 interface Monitor mode – ability to monitor transmission
on RS-485 interface and react to the value of the selected register.
•10/100 BASE-T Ethernet interface (option)
•protocol: Modbus TCP/IP, HTTP, FTP,
•services: WWW server, FTP server, DHCP client

3. BASIC REQUIREMENTS,
OPERATIONAL SAFETY
The transducer meets the requirements of EN 61010-1 standard
in terms of operational safety.
Safety precautions:
•The assembly and installation of electrical connections must be
carried out by a person authorized to install electrical equipment.
•Before switching the transducer on, one must check the correct-
ness of connections.
•The device is destined to be installed and used in industrial electro-
magnetic environment conditions.
•The building installation should be equipped with a switch
or an automatic circuit breaker located near the device,
which should be easy accessible by the operator and properly
marked.
•Removal of the transducer housing during the warranty period
may cause its invalidation.

4. INSTALLATION
4.1. Mounting method
PCE-P30Utransducers should be mounted on a 35 mm rail
bracket according to PN-EN 60715. Dimensions and method of
mounting are shown in figure 2.
Fig.2. Overall dimensions and method of mounting
the transducer.

For the connection of input signals in environments with a high noise
level, shielded wires should be used.

5. OPERATION
5.1 PCE-P30U transducer front panel description

Note: The memory card (option) should be inserted to the transducer
slot with contacts facing down
LED indicator description:
RX – green diode – Data reception on RS-485 indicator
TX – yellow diode – Data transmission on RS-485 indicator

12
M – red diode – full internal memory indicator or writing file
to SD/SDHC memory indicator, when the internal
memory usage exceeds 95%, the diode is
constantly on, if the transducer operates
with an installed memory card, then the LED flashes
when data is being written on the card.
A1 – red diode – indicator of switching on the rst alarm
A2 – red diode – indicator of switching on the second alarm
or 24V d.c. power supply
Power indicator – green diode.
5.2. Messages after switching on the power
After connecting external signals and switch the power supply on
which is signalled with a green LED (power indicator), the transdu-
cer displays the type, current rmware version and the serial number.
If the transducer is equipped with Ethernet interface (PCE-P30U-X2XXXXXX)
IP address is displayed after serial number (stored in memory or received
from the DHCP server).

with an Ethernet interface.

net interface.

5.3. Key functions
5.3.1. Individual key functions
- accept key
• enters programming mode (hold for about 3 seconds),
•navigates the menu – level select,
• enters parameter value change mode,
• accepts the changed parameter value,
• changes the content displayed in the lower line of the display,
•switching the transducer power supply on while holding this key
enters the software update mode through the RS-485 interface,
connection parameters: rate 9600 kb/s, mode 8N2.
- increase value key
•displays the maximum value of the main input,
• enters the parameters group level,
• navigates the selected level
•changes the value of a selected parameter – increase value,
After about ve seconds, the transducer automatically
switches to operating mode; it makes a measurement and converts it
into an analog output signal. It displays the measured value in the top
row of the display and auxiliary information in the bottom row of the dis-
play (section 5.5.4). The LED indicator signals the transmission status
on the RS-485 interface, status of the internal memory use and alarm
states. If transducer is equipped with an Ethernet interface, Ethernet
services start-up: WWW server, FTP server, TCP/IP Modbus

14
- change digit key
• displays the minimum value of the main input,
• enters the parameters group level,
• navigates the selected level,
•changes the value of a selected parameter – switches to the sub-
sequent digit,
•switching the transducer power supply on while holding this key
enters the software update mode through the RS-485 interface,
connection parameters: rate 15200 kb/s, mode 8N2.
- cancel key
•enters the transducer parameters preview menu (hold for about
3 seconds),
•exits the transducer parameters preview menu,
• changes the content displayed in the lower line of the display,
• cancel the parameter change,
•completely cancels the programming mode (hold for about
3 seconds).
•switching the transducer power supply on while holding the key for-
ces reading transducer conguration from PCE-P30U_PAR.CON
le stored on an external SD/SDHC memory card or in the internal
le system memory (depending on the manufacturing variant).

5.3.2. Functions of key combinations
- hold for about 3 seconds
•clear alarm indication; this action works only when the alarm
indication memory function is switched on;
- hold for about 1 second
•clears the maximum value for the measured value
- hold for about 1 second
• clears the minimum value for the measured value
- hold for about 1 second
•unmounts the SD/SDHC memory card enabling safe removal –
for transducer equipped with an external SD/SDHC memory slot
- hold for about 1 second
•force start copying the archive from the internal memory into
the SD/SDHC memory card– for transducer equipped with
an external SD/SDHC memory slot
•force start copying the archive from the internal memory
to the le system memory – for transducer equipped
with an Ethernet interface; this action enables downloading
current archive data les from the transducer via FTP protocol
Push and hold the programming key for about
3 seconds to enter the programming matrix. The programming matrix
can be protected with a safety code.

5.4. Programming transducer parameters
Press and hold for about 3 seconds key
to enter the programming matrix. If access is password protected,
transducer will ask for password. If the entered password is incorrect,
Err.Code message will be displayed. Correct password enables
access to the programming matrix. Fig. 8 shows the matrix
in the programming mode. Use or to select
the menu level or navigate the parameters of a given sub-level.
The parameter symbol is displayed at the upper line of the display,
while the parameter is displayed at the lower line of the display.
Press to edit parameter. Press to cancel changing
parameter. Press and hold to exit the programming matrix
and enter the measurement mode. If the transducer remains inactive
for 30 seconds in the parameter programming mode, it will exit the pro-
gramming mode and display the displayed value.
