e-TRIM Overview

WARNING:

772-0060 for questions about mounting and cooling.

IMPORTANT: When first warming up, the 02 percentage for each burner will read 99.99%. This is

sensor. Call Super Systems Inc. technical support at 513-772-0060 for assistance.

e-TRIM is designed to be installed on indirect fired burners. With e-TRIM, the operator will be
able to monitor and alarm based on a desired oxygen percentage during high fire. The system
will provide continuous indication of oxygen and will warn the operator when the burner is
outside of the desired oxygen band.

Additionally, e-TRIM is equipped with a critical alarm. This alarm is designed to provide an
audible and visual indication when a burner is either not lit or running extremely lean.

Typical settings are as follows:
Desired percent on high fire is 2% per the DOE, which would provide 10% excess air. The band
alarm should be set to 1%. When on high-fire, if the reading is below 1% or above 3%, the
screen will show an out-of-band condition. Additionally, SSi recommends the critical alarm be
set to 8%. When on high fire, if the reading goes above 8% and the trim delay expires, the horn
will sound. This is notification that a burner that is not lit or is extremely lean.

It is recommended that the desired oxygen percentage be verified with the burner manufacturer
prior to adjusting. It is important to make sure that the Carbon Monoxide PPM limit is not
increased when adjusting the burner.

e-TRIM electronics enclosure must not be exposed to temperatures above 120°F (49°C). It
should not be mounted on the furnace unless proper cooling is installed. Contact SSi at 513-

Sensor installation:
The sensor should be mounted on the exhaust leg of the burner prior to any gaps or possible air
drafts. The sensor should be installed in a location that will not exceed 1000° F on high fire.

Sensor Mounting:
The thread for the e-TRIM O

sensor is M18 x 1.5. It is a metric thread.

expected, and the value will change to an appropriate value within 30 to 60 seconds. If the 02
percentage should read 99.99% at any time other than during the warm-up period or if it
remains 99.99% after the first two minutes of operation, there may be a problem with the

Examples of e-TRIM installations are shown in Appendix D – Typical Installations Based on

This manual was written with oxygen readings from the ambient air, not in a valid run-

time environment.

This is the main screen for the e-TRIM Touchscreen software. Once the software has booted up,
this screen will be displayed. This screen will list the Burners, along with the % Oxygen
reading, the Status of each burner, and the status of high fire or low fire. The possible
messages are:

•

– everything (coms, burner conditions, etc.) is ok.

•

•

- there is bad communication to the sensor board.
– there is an out of band condition, and the system is waiting for the

delay timer to expire.

•

- The burner is out of band. Status Disabled – The board has been

disabled.

•

•

- There is a critical alarm active.
– The critical alarm is active, but the alarm has been acknowledged.

The yellow icon signals that the burner is on high fire.

made in accordance with the electrical schematic located at the back of this manual, with 4 to
20mA corresponding proportionally to 0 to 25% oxygen. The ability to retransmit the oxygen
signal requires circuit boards that are not part of the standard system. For additional
information regarding this feature, please contact Super Systems Inc. (513-772-0060).

System Setup

This option will allow the user to make changes to the current system settings. Currently, there
are six options to modify.

Alarm Delay
This setting is the number of seconds that the system will wait before showing an out of band
alarm condition, if an alarm condition is present. This is entered in seconds. The range is

.

Alarm Band
This setting is the band for the boards’ setpoint. If the setpoint is 3%, and the band is 2%, then
an alarm indication condition will not be present until the reading goes under 1% or above 5%.
This is entered in percentages. The range is 0% to 20.9%.

The alarm band will not
sound the horn and is for indication only. Output 7 can be wired to an external horn or light if
needed (see the electrical prints for termination details).
