Relay PCA 04523 Addendum to E-Series Operator Manuals
1. INTRODUCTION
This addendum documents a recent upgrade to the relay card installed in some of the M100E,
M200E and M400E series analyzers. Specifically, a new relay PCA design, P/N 04523 replaces P/N
03955 and all of its versions in the following instruments.
It also corrects several errors related to the function of the relay PCA.

For those instruments, the information included in this addendum supersedes the information
related to the relay PCA that appears in the chapters on Theory of Operation
and Troubleshooting
& Repair of your M100E/M200E/M400E operator’s manual’s.
Because the operator’s manual for each model family of the E-Series instruments is slightly
different there is no direct correspondence between the sections and chapters of this addendum
and those of the manual.
1.1. What’s the Same
In most respects the electronic operation of the Relay PCA 04523 is the same as Relay PCA
03955.
Both are used by the CPU to operate various AC and DC heaters that control the
temperature of key components of the E-Series analyzers to such as sensor modules,
reaction cells and converters as well as certain optional components such as IZS
permeation tubes.
In both cases a set of configuration jumpers located on the relay card is used to configure
the heaters for 110 VAC, 60 Hz vs. 230 VAC, 50 Hz operation.
Both Relay cards, based on commands from the CPU received over the
energize/de-energize the various solenoid valves used to control the sample gas path of
the analyzers (e.g. reference/measure valves; zero-span-cal valve options; IZS options;
etc.)
Both distribute the AC and DC power to the various electrically powered components and
assemblies for the instrument.
Both include a special watchdog circuit watches that will automatically shut of all valves as
well as turn off the UV Source(s) and all heaters should either the CPU cease issuing
commands or the I
2C
bus fail. In both cases the sample pump will continue to run.

1.2. What’s Different
The major differences between the Relay PCA 04523 and Relay PCA 03955 are:
On instruments with internal pumps, the pump is now configured for use with 110 VAC, 60
Hz vs. 220 VAC, 50 Hz operation by a set of configuration jumpers on the Relay PCA.
Previously a set of inline connectors and wiring harnesses performed this function.
The configurability of the two thermocouple inputs has been expanded to allow for both
grounded and ungrounded thermocouples
A retainer plate has been added to the 045230200 version to keep the solid state AC
power relays securely inserted in their sockets.
Because the board has been physically changes, locations of components such as jumper
blocks, connectors and status LED’s have changed.
1.3. Relay PCA Location and Layout
Generally the relay PCA is located in the right-rear quadrant of the analyzer and is mounted
vertically on the back side of the same bracket as the instrument’s DC power supplies, however
the exact location of the relay PCA may differ from model to model. Please check the Getting
Started chapter of your M100E/M200E/M400E operator’s manual.

A
There are two versions of the new relay card. Table 1-1 above cross references the PCA version
with the various E-series analyzer models.
1.3.1. Version 045230200
This is the most commonly used version of the Relay PCA. It includes a bank of solid state AC
relays. This version is installed in analyzers where components such as AC powered heaters must
be turned ON & OFF. A retainer plate is installed over the relay to keep them securely seated in
their sockets.

1.3.2. Version 045230100
This is the base version of the Relay PCA. It does not include the AC relays and is used in
instruments where there are no AC powered components requiring control. A plastic insulating
safety shield covers the empty AC Relay sockets (See Figure 1-3)
CAUTION
Never remove this safety shield while the instrument is plugged in and
turned on. The contacts of the AC relay sockets beneath the shield carr y
high AC voltages even when no relays are present

2.1.1. AC Power Configuration
The E-Series digital electronic systems will operate wit h any of the specified power regimes. As
long as instrument is connected to 100-120 VAC or 220-240 VAC at either 50 or 60 Hz it will turn
on and after about 30 seconds show a front panel display. Internally, the status LEDs located on
the Relay PCA, Motherboard and CPU should turn on as soon as the power is supplied.
On the other hand, some of the analyzer’s non-digital components, such as the pump and the
various AC powered heaters must be properly configured for the type of power being supplied to
the instrument. Figure 2-3 shows the location of the various sets of AC Configuration jumpers.

Previously, in analyzer models with intern al pumps, the AC power for the pump came
directly from the instrument back panel. The 04523 version handles all AC and DC power
distribution including power to the pump.
Prior to this change, configuring the pump for compatibility with various line voltages and
frequencies was done with a set of hard-wired, in-line connections. The Relay PCA
04523, now includes a set of jumpers that perform this function. This change increase
reliability and simplifies troubleshooting and repair operation s .
The Relay PCA 04523, includes a set of jumpers that connect AC power to heaters
included in several optional items, such as the IZS valve option and the O
sensor option

available on the M100E, M200E and M400E series instruments. In earlier versions of the
relay PCA this was also handled by in-line connections.

2.1.1.3. AC Configuration –Heaters for Option Packages (JP6)
Both the IZS valve option or an O2 sensor options include AC heaters that maintain an optimum
operating temperature for key components of those options. Jumper set JP6 is used to connect
the heaters associated with those options to AC power. Since these heaters work with either
110/155 VAC or 220/240 VAC, there is only one jumper configuration.

2.2. Valve Control
Other than the location of the connectors and control chips on the PCA (see Figure 1-1 above),
there have been no significant changes to the method by which the E-Series instruments’ various
valves and valve options are controlled.

Addendum to E-Series Operator Manuals Relay PCA 04523
2.3. Status LEDs & Watch Dog Circuitry
Like the previous version, the status LED’s on the Relay PCA 04523 includes thirteen LEDs that
indicate the status of the analyzer’s heaters, valves and other general operating conditions. Since
the functions represented by these LED differs from model to model, check your
M100E/M200E/M400E operator’s manual for their exact assignments (this can normally be found
in the section on Electronic Theory of Operation).
While the functional assignments for the LED’s of each model have remained unchanged their
location on the PCA is different. See Figure 2-3 of this addendum for the new locations.
2.3.1. Watchdog Indicator (D1)
The most important of the status LED’s on the relay board is the red I1C Bus watch-dog LED. It is
controlled directly analyzer’s CPU over the I
status of D1. Should this LED ever stay ON or OFF for 30 seconds, indicating that the CPU or I

While the role of the heater control lop for the E-Series analyzers is basically unchanged from the
previous version (see Figure 2-4) the configurability of the Thermocouple inputs has been
enhanced. Previously, the two T/C inputs could be configured for either type-T or type-K
thermocouples. The 04523 relay PCA adds the following.
Both T/C’s can now be configured as either grounded or ungrounded thermocouples.
Standard configuration of the both type of thermocouples is 10 mV/°C. In order to
accommodate the M200EH’s Mini High-Con converter option, a type-K; 5mV/°C output
configuration has been added.

2.4.1. Thermocouple Inputs and Configuration Jumper (JP5)
Although the 04523 relay PCA supports two thermocouple inputs, the current M100E/M200E
series analyzers only utilize one and the M400E series analyzers none. By default, this single
thermocouple input is plugged into the TC1 input (J15). TC2 (J 16) is currently not used. See

3. TROUBLE SHOOTING AND REPAIR
General Trouble shooting hints for the relay PCA are the same as described for the previous
versions for the PCA. See Chapter 11 of your M100E/M200E/M400E operator’s manual for more
information.
3.1. Removing / Replacing the Relay PCA from the Instrument
The Relay retainer plate installed on the 045230200 PCA (version with AC relays) covers the lower
right mounting screw of the relay PCA. Therefore, when removing the relay PCA, the retainer
plate must be removed first.
