1 Introduction
The Honeywell ERX 350 is a microprocessor-based, stand-alone, self-powered data recorder that
measures gas pressure(s), gas temperature, case temperature, and power supply voltages. Sampled
measurements, logged Audit Trail data, Alarms entries, User change events, and operating parameters are
stored in non-volatile memory and may be retrieved directly with a laptop computer, PC, mobile devices,
or remotely via modem. ERX 350 Recorder is capable of recording audit trail data into (up to five)
independent Loggers. Each of the loggers can be configured for; number of items, logging interval and
record size. Recorder configuration (and other activity) is possible via the HMI feature.
The ERX 350 offers large feature set along with a path forward to support new technologies.
The ERX 350 installation consists of mounting and wiring ERX 350 according to the instructions given in
the User’s Manual. Read the installation information provided in the ERX 350 User’s Manual and refer to
the section “Model number interpretation” for more details on ERX 350 model you have selected.

2 Powering the ERX 350
2.1 Battery Power Units
The Connections are made at P5 connector on the ERX 350 I/O Board. The ERX 350 unit can be operated
from the following battery power:
40-6050 (4-cell Alkaline) – 5 year operating life under specified conditions
40-6048 (2-cell Lithium)
Dual set of 40-6048 (2-cell Lithium) – extended life or heavy usage / comms applications.
Item 1061 (Battery Type) is used to select the type of battery pack that is to power the instrument.  Verify
item 1061 is correctly configured for the installed battery pack.
0 = 4 D-Cell Alkaline Receptacle Pack, for EC350 only - Default
1 = 2 D-Cell Lithium Sealed Pack, for EC350 only
2 = Dual 2 D-Cell Lithium Sealed Packs (connected in parallel), for EC350 only
Figure 2-1: 40-6050 (4-cell Alkaline)

The graphic below shows an alkaline battery pack connected. The ERX 350 I/O Board is on the right.
Note the twin connector (two connector pair) provided for the battery connection. Only one is being used
in this photo.
Figure 2-3: Alkaline Battery Pack Connected
2.2 External Supply Power Units
The Connections are made at TB1 connector on the ERX 350 I/O Board.
2.2.1 Specifications for external power supply
The input voltage range for using an externally supplied DC power source is +5.0 to +15.0 VDC.
The Honeywell power 9 VDC, 400 mA power pack (p/n: 40-2291) can be used as an external
power source
Connections for the external supply are made at connector TB1 on the ERX 350 I/O Board.
Terminal-1 of TB1 closest to the top of the I/O Board is negative (-) and Terminal-3 is positive
(+) input. These Battery Packs can be connected to the I/O board using cable p/n: 40-6045.
A backup battery pack may also be installed to keep power on the instrument in situations
where the external power is interrupted.
Notice: for Class 1, Div. 2 compliant installations, only the following Battery Packs are
approved:
40-6048 (2-cell Lithium)
40-6050 (4-cell Alkaline)
40-6064 (4-cell Alkaline with 47 ohm Res).
Configure the External Supply Low Alarm Limit (Item 795) to a value of 5.0 to 7.0 volts. Note
that the default value of Item 795 is set to -1.0 to effectively disable the Alarm Item 796 when
external supply is not being used.

2.2.2 General Power Supply Notes:
Supply power is measured on a 10-minute interval (battery / external supply voltages)
An Item is not used to choose between externally supply and battery powered
For Alarm triggering – three (3) consecutively low readings are required to the trip the associate
Alarm. This is done to help guard against falsely setting alarm due to a supply glitch
The Low Battery Voltage Alarm (Item 99) will not set if there is an External Supply voltage at
TB1 greater than the Battery voltage by over 1.0 volt

3.1 I/O Board Connections
Note:
ERX 350 does not use Pulse Outputs A – B – C
Metrological Jumper is generally not required for ERX (Recorders)
Digital Input connections are made at: SW1 – SW2 – SW3 (Input ‘SW4’ is not utilized)

4 Connecting a Pressure Line
Shown below are the locations for P1 and P2 Pressure Transducer connectors.
Use a pressure connector kit to connect the required pressure line(s) to the ¼ inch NPT fittings on the
back side of the ERX 350 enclosure.
Hold pipe wrench on flats when installing a pressure line on the pressure transducer connector to ensure
proper sealing and to avoid stress loading on the composite case.
Figure 4-1: Locations for P1 and P2 Pressure Transducer connectors
Note: To avoid over-pressurizing the transducers, it is extremely important to ensure the pressure
transducer(s) can handle the pressure from the gas line(s).
Check Items 570 (P1 Transducer Range) / 571 (P2 Transducer Range) BEFORE applying live gas
pressure to the ERX 350.
