HOW TO DISMANTLE SYSTEM 4000

First, remember to demount the connectors with hazardous voltages.

When front LED lights red / display shows AO.ER:

PR 4114 is designed with a high safety level. Therefore, a continuous measure-
ment of the outgoing current is carried out on a 4...20 mA output signal. If
the current is 0, a fatal error mode occurs and the red front LED switches on.
If the analogue output is not used, pins 11 and 12 must be short-circuited in
order for the module to function. The fatal error mode can only be reset by
switching off and then switching on the supply voltage to the module.

UNIVERSAL TRANSMITTER
PReasy 4114
• Input for RTD, TC, Ohm, potentiometer, mA and V
• 2-wire supply > 16 V
• FM-approved for installation in Div. 2
• Output for current and voltage
• Universal AC or DC supply

Advanced features:

• Programmable by way of detachable display front (4501), process calibration,
signal simulation, password protection, error diagnostics and help text
available in several languages.

Application:

• Linearised, electronic temperature measurement with RTD or TC sensor.
• Conversion of linear resistance variation to a standard analogue current /
voltage signal, i.e. from solenoids and butterfly valves or linear movements
with attached potentio meter.
• Power supply and signal isolator for 2-wire transmitters.
• Process control with standard analogue output.
• Galvanic separation of analogue signals and measurement of floating signals.
• The 4114 is designed according to strict safety requirements and is thus
suitable for application in SIL 2 installations.

Technical characteristics:

• When 4114 is used in combination with the 4501 display / programming front,
all operational parameters can be modified to suit any application. As the
4114 is designed with electronic hardware switches, it is not necessary to
open the module for setting of DIP-switches.
• A green / red front LED indicates normal operation and malfunction.
• Continuous check of vital stored data for safety reasons.
• 3-port 2.3 kVAC galvanic isolation.
