1. INTRODUCTION
1.1 OVERVIEW
The Edison model 1604 monitor is designed to provide simultaneous, continuous surveillance of up to 4
RTD’s (Resistance Temperature Detectors). RTD sensors are electronically measured and their temper-
ature is compared to the pre-selected trip points within the monitor. When the RTD sensor temperature
equals or exceeds the pre-selected value entered by the administrator, a common system alarm relay
will trip, and then the alarm detail can be viewed.
Different combinations of configuration for each channel are available for alarm on rising or falling. The
temperature trip relay is internal to the main monitor unit. Each channel allows the administrator to insert
a memo field that can be displayed in the event of an alarm. Incoming alarms can be viewed in detail at
the display, while the event results are saved in a history text file. The 1604 monitor accepts industrial
standard RTD inputs for Nickel, Platinum and Copper characteristics. Installations can include from 1 to
4 RTD sensors. There is no calibration required for the monitor.
Proprietary software and hardware within the monitor enables anyone to learn to operate the system
quickly. System design is based on 24 bit microprocessor technology to ensure high resolution and fast
response time. The monitor is available for 115, 230VAC or 24VDC operation.
Programming is implemented by utilizing a standard USB PC keyboard, temporarily connected to the
front bezel. The administrator programs preset temperature values into the monitor, as well as sensor-
specific messages. At completion of programming, a configuration report can be printed out for review.
History reports are available and can be viewed on the monitor or printed.

2. SYSTEM INSTALLATION
2.1 ENVIRONMENTAL CONSIDERATIONS
The main monitor unit behind the front panel assembly must be located in an environment free of rain,
airborne particles and condensation. The front of the panel may be exposed to a wet and dusty environ-
ment, provided the procedure in locating the housing flange gasket for the front of the monitor is utilized.
2.2 MONITOR INSTALLATION
Refer to figures 3,4 and 5 to identify correct panel cutout to install the monitor housing. Use the supplied
hardware to mount the monitor. Carefully remove the four front bezel screws to expose the chassis
mounting holes. Mount the monitor housing with the mounting flange located on the front side of a se-
cure panel that can accommodate the weight and all necessary wiring. Allocate spare room behind the
monitor to gain access to the terminal strips. Do not allow any debris to fall into the housing. After secur-
ing the housing to its panel, locate the front bezel assembly back into place by first aligning the electrical
connectors and then tighten the four mounting screws.
NOTE: The flange bezel gasket is not supplied, and may be ordered through your distributor by specify-
ing part number 1604-2814. This gasket is utilized if the monitor is subjected to dusty or wet environ-
ments in front of the mounting panel.
2.3 MONITOR FIELD WIRE SUGGESTION
Terminals located at TB2 & TB3 are provided to wire the power, system fault and alarm relay. The use
of stranded wiring is recommended for all relay connections. Do not allow frayed wires to come in con-
tact with its adjoining terminal. Cut approximately .25” insulation from the wire, twist the strands togeth-
er, insert the wire in its respective terminal strip, and then tighten the terminal strip, utilizing the supplied
screwdriver.
2.4 EARTH GROUND CONNECTION
Connect an earth ground wire to TB2-3 on the monitor as indicated in figure 6. Use at least a 14 gage
wire or larger to ensure that there is no more than one ohm total resistance between the monitor chassis
and earth ground. Do not use the mechanical assembly as to substitute for an electrical ground connec-
tion.
2.5 RTD CONNECTIONS
Typically, two-wire RTD’s are utilized in installations but a three-wire may be utilized for higher accuracy.
Two-wire RTD’s are less expensive than three-wire and should be adequate for the average industrial
application. Three-wire RTD’s are supplied with two leads the same color and the third a different color.
Connect the RTD wires to the monitor TB1 as indicated in figure 6.
2.6 SYSTEM FAULT RELAY CONNECTIONS
TB3 terminals on figure 6 provide a customer-accessible dry relay contact. Connect devices to this form
C relay to monitor a system fault. The SPDT fault relay is rated in the specifications section and is nor-
mally energized for failsafe operation. The fault relay is not required in an installation but helps for any
diagnostic problems. Refer to section 10 for fault descriptions.
WARNING - THE EARTH GROUND IS IMPORTANT TO PREVENT A POSSIBLE ELECTRI-
CAL SHOCK HAZARD TO THE USER.
CAUTION - CONNECTING ANY VOLTAGES HIGHER THAN 5VDC TO THE RTD INPUT
TERMINAL TB1, COULD RESULT IN DAMAGING THE MONITOR AND VOIDING THE
WARRANTY.

Page 10
2.7 TEMPERATURE ALARM RELAY
Refer to the TB3 terminal strip in figure 6 for wiring the alarm relay dry contact. Connect devices to this
form C, (SPDT) relay to monitor the set point of any alarming RTD sensor. This relay is common to the
four channels of the monitor. The alarm relay will change state when a temperature enters the adminis-
trator defined temperature set point. The alarm relay functions with alarms on rising or falling.
NOTE: The monitor comes with all RTD channels disabled to alleviate possible alarms when the monitor
is first powered up.
2.8 POWER CONNECTION
Depending on the monitor power supply, connect the power requirement to the monitor terminal TB2 as
indicated in figure 6. Verify on the product ID label the correct power source prior to applying power to
the monitor. After all hardware devices have been mounted and connected together, power may be ap-
plied to the monitor.
2.9 INTERNAL COMPONENT BOARD DESCRIPTIONS
The three boards listed below are installed in the monitor and are not a component to be repaired by
unauthorized personnel. For repair, the monitor must be sent to the distributor where it was purchased.
2.10 PROCESSOR BOARD
This board incorporates the microprocessor, memory, display and all necessary components to allow
the process function of the monitor.
2.11 POWER SUPPLY BOARD
Power requirements for the monitor are provided by the power supply board. The input of the power
supply is transient protected from surges. The monitor power input is fuse protected and identified on
the circuit board. This fuse, (F1) is a 5mm, 1A Slo-blo. Refer to the monitor identification label to verify
the power supply voltage rating.
2.12 REAR TERMINAL BOARD

3. MONITOR PROGRAMMING
3.1 GENERAL
The viewing display is made up of 80 characters that are placed in a 4-row by 20-character matrix. The
display will remain in a low intensity mode until there is an alarm, keypad or keyboard activity. After the
activity has been discontinued, the display will resume its normal intensity in 15 minutes. The Edison
series 1604 monitor utilizes a USB keyboard to program, and requires no external computer. The key-
pad on the monitor front panel is utilized to view data, acknowledge alarms and change temperature
from degrees F to C. To program, the keyboard must be connected to the monitor. The keyboard con-
nector can be inserted whether the monitor is powered or not, but do not remove keyboard while in the
configuration mode.

NOTE: On a 3-wire RTD, the red or either one of the white signal wires opening are considered the
problem. Also, either white wire shorting to the red can be the problem. Shorted or singular opened
white wires will not cause a fault but will influence the temperature accuracy, depending on the length of
the RTD wires.
NOTE: Should an open or short fault occur, the display will indicate a fault and not a temperature alarm.

When the menu settings are saved, the temperature F/C indication will also be saved based on its last
indication. Changing the F/C in other menus retains this data but will default back to the selected F/C
when re-entering the menus, occurring alarms and reports.

5.1 SYSTEM STATUS
The words “SYSTEM OK” will remain on the display unless an alarm, fault or enter program condition
occurs.
5.2 TEMPERATURE ALARMS
In the event any temperature attains an alarm set point, the common alarm relay (TB1) will trip as indi-
cated in the configuration menu. The beeper will turn on, and the display will brighten from its low inten-
sity to bright mode to identify the alarm parameters. The → NXT ALRM line will appear when there are
other active alarms to view. Navigate to menus to view and reset any alarms.
6. MULTIPLE TEMPERATURE ALARMS
In the event that multiple alarms occur, the first set point to sustain its threshold will be displayed.
Alarms that are received are placed in chronological order. The display automatically jumps to the next
incoming alarm if the acknowledgment is left unattended. The alarm-viewing structure of the display is
set up as a continuous spreadsheet so the administrator can CURSOR ► to a specific RTD number in
alarm and then CURSOR ▼ to the details. At any time cursor left Ctrl + CURSOR ► or right to jump to
the next column of another RTD. If the cursor is not in the top alarm menu and then shifted ◄► to the
next alarm, the cursor will jump to the top menu. The ALARM indicator flashes when the alarm is active
and goes solid when the alarm clears. When the alarm clears, reset it by selecting the ACK button on
the face plate.
