N o t i c e : A small red LED located on the top of the hand
held programmer near the external connections blinks when the hand held programmer is com­municating with a trip unit.
2-2.1 INTERNAL BATTERY POWER
A 9-volt battery compartment with a slide out access cover located on the back of the device provides easy access to an internal 9-volt battery (Figure 2-4). The number of continuous operation hours the 9-volt battery will support depends upon the type of battery used. Refer to Table 2.2 for information about battery choices.
When an auxiliary power supply is not being used, the programmer will automatically turn off to save battery power or provide an indication of insufficient power under the following conditions:
1. The programmer turns itself off when the battery
power available is not sufficient to carry out all pro­grammer functions, including both powering of the programmer and the trip unit. When this occurs the battery should be replaced.
Figure 2-3 OPTIMizer Hinged Protective Cover (Open Position)
Effective 8/99
I.B. 29C892B

Figure 2-4 OPTIMizer Battery Compartment with Battery Installed
2. If none of the pushbuttons on the operator panel are used for approximately 2 1/2 minutes, the program­mer turns itself off. This includes the performance of a non-trip test. External power is required to perform a trip test. Refer to the next paragraph for external power details.
2-2.2 EXTERNAL CONNECTIONS
Three receptacles are provided on the top of the device, one for an external power connection and two different means for connecting the programmer to the trip unit (Figure 2-2).
External Power Connection
Use external power to:
• Save internal battery power
• Perform trip test on circuit breaker
• Communicate over INCOM
External power is provided by connecting an Auxiliary Power Module (Catalog Number PRTAAPM) to the OPTIMizer through the 2-pin male receptacle. The Auxiliary Power Module requires a 120 Vac 50/60 Hz input and delivers a 32 Vdc 4 VA output (Figures 2-2 and 2-5). Note that OPTIM trip units with external power connections (K, L and N) operate from a 24 Vdc power source.
Figure 2-5 Auxiliary Power Module Shown Connected to OPTIMizer
Direct Breaker Connection
The first method for connecting the hand held program­mer to the trip unit is by means of the 8 conductor cus­tom phone cord provided with the programmer. One end plugs into the front panel of the trip unit and the other end into a custom phone jack port (HDR1) on the top of the programmer. This direct connection is intended only for use with the hand held programmer, and is normally associated with the direct programming of individual trip units (Figures 1-1, 2-2 and 2-6).
Network Connection
The second means for connecting the hand held pro­grammer is through the 3-pin male connector (J2) locat­ed on the top of the programmer. This connection is made through an INCOM shielded twisted-pair. The hand held programmer has an internal INCOM trans­former permitting it to communicate over the network. This is the method normally associated with network pro­gramming (Figure 2 - 2). Auxiliary power to the OPTIMizer is required to communicate over the INCOM network.
Notice: A direct connection will override an INCOM
connection. This will also signal a no response alarm on other network devices.

Figure 2-6 OPTIMizer Shown Connected to Series C L­Frame Circuit Breaker
2-3 OPERATOR PANEL
The operator panel provides a means to initially assign addresses, select baud rates, configure trip units, dis­play information, and perform testing (Figure 2-1). For the purpose of familiarization, the panel is divided into two sub-sections:
• Pushbuttons
• Display
2-3.1 PUSHBUTTONS
The operator panel contains eight membrane pushbut­tons. Pushbuttons generally accomplish their function when pressed and released. Variations in the use of a particular pushbutton are detailed in the description for that particular pushbutton. The pushbuttons are catego­rized as follows:
• General Pushbuttons
• View Functions Pushbuttons
• Edit Values Pushbuttons
Figure 2-7 General Pushbuttons
On/Off Pushbutton
The On/Off pushbutton turns the hand held programmer on and off. To achieve power-up, the pushbutton must be pushed and held for approximately one second. The programmer cannot be turned off while Find Baud/Addr is displayed. When the programmer is on, power is delivered to the trip unit.
Save Pushbutton The Save pushbutton is used in conjunction with the
Select pushbutton to cause any programmer initiated
change to be saved to memory. The Save pushbutton must be pressed and held followed by depression of the Select pushbutton to accomplish the saving function. Changes must be saved individually before moving to another menu. This feature minimizes the possibility that re-programming would be required if the programmer turns itself off during the programming process.
2-3.3 VIEW FUNCTIONS PUSHBUTTONS (Figure 2-8)
2-3.2 GENERAL PUSHBUTTONS (Figure 2-7)
Select Pushbutton
The Select pushbutton performs two functions. First, it is used in conjunction with the Save pushbutton to save
Effective 8/99
I.B. 29C892B
changes to memory as previously described. In addition, the Select pushbutton by itself causes the programmer to select a particular category indicated by the blinking cur­sor and move further into that particular selected menu.
Up-Arrow Pushbutton
The Up-Arrow pushbutton is used to move the blinking cursor back to the first selection Select Address (SA) when the programmer is displaying the top level menu (Figure 2-9). It is similar to the Escape Key of a PC. If the programmer is displaying a lower level menu, use of this pushbutton moves the display back one menu level, eventually ending at SA.
Right-Arrow Pushbutton
The Right-Arrow pushbutton moves the blinking cursor horizontally to the right in the display from category to category. Continued use of this pushbutton will wrap around and eventually return to the starting category.
Left-Arrow Pushbutton
The Left-Arrow pushbutton performs the same function as the previously described Right-Arrow pushbutton except movement of the blinking cursor is horizontally to the left.

The Down pushbutton performs the same function as the previously described Up pushbutton except move­ment is in the opposite direction down through the val­ues and/or selections.
2-3.5 DISPLAY
N o t i c e : This manual utilizes a gray rectangular box
underlined in black to represent a blinking cursor in all illustrations of the programmer’s display (Figure 2-9).
A 2-line, 16-character per line liquid crystal display is used to display all trip unit data, setpoints and mes-
I.B. 29C892B
sages. The brightness of the display can be adjusted through the use of a small, recessed adjusting screw located in the top side of the programmer (Figure 2-2).
The first line of the display is normally used to show the main menu selection possibilities. A blinking cursor indi­cates which category on the first line is active. The sec­ond line of the display either defines the first line catego­ry highlighted by the blinking cursor or, in lower level menus, presents a field that is capable of being changed, as indicated by a blinking cursor. Note in Figure 2 - 9 t h a t the blinking cursor is positioned just to the left of S A i n the top line of the display. Note also that the second dis­play line defines that category as Select Address. Table 2 . 1 outlines all the displayed menu items that can be encountered in the OPTIMizer display along with their specific definitions. Figure 2 - 1 1 shows the twelve avail- able options accessible from the main menu.

SECTION 3: OPERATION AND USE
3-1 GENERAL
This section specifically describes the effective operation and functional use of the OPTIMizer Hand Held Pro­grammer. The OPTIMizer is used to access the many capabilities of OPTIM 550, 750 and 1050 Trip Units. Specific details associated with the trip units are covered in Instruction Book 29C891 entitled “Instructions for Installation, Operation and Maintenance of Cutler­Hammer Digitrip OPTIM Trip Units.” It is recommended that the operator review the material presented in Section 2 prior to operating and using the hand held pro­g r a m m e r .
Familiarization with the information presented in Table 2 . 1 will prove helpful. Table 2 . 1 outlines the menu items accessed from the top level menu (Figure 2 - 9). Menu item definitions are provided in the user friendly display with additional explanatory information provided in Table 2 . 1. In addition, an OPTIMizer Menu Diagram provides an overall picture of the device’s capabilities (Figure 3 - 1) . This diagram is also shown on the OPTIMizer back panel for quick and easy reference (Figure 2 - 4) .
Section 3 covers the operation and use of the OPTIMizer. It is broken down into the following general categories:
• Getting Started
• Power Application
• Security Password
• Assign Address/Select Baud Rate
• Configure Trip Unit
• Displayed Information
• Test Trip Unit
3-2 GETTING STARTED
The OPTIMizer Hand Held Programmer is a simple to use device. Before applying power and using the device, it is recommended that the following preliminary steps be taken:
Step 1: If the programmer is to be operated by battery
power only, be sure that a fresh battery is properly installed. Refer to paragraph 2-2.1 for battery information.
Step 2: If power will be supplied by an Auxiliary Power
Module, be certain that the Auxiliary Power Module is connected to the appropriate 120 Vac source and the OPTIMizer Hand Held Programmer. Refer to paragraph 2-2.2 for details on an external power connection.
Notice: Keep in mind that an Auxiliary Power Module
is always required if a “Trip” Test is to be per­formed on a circuit breaker.
Step 3: When a Direct Breaker Connection is being
made, plug either end of the custom phone cord into the phone jack port on the top of the programmer first, and then plug the other end into the port provided on the trip unit. The con­nections should be made before power is applied. Refer to paragraph 2-2.2 for details on a Direct Breaker Connection.
Notice: A direct breaker connection will override an
INCOM connection. This will also signal a no response alarm on other network devices. Clear the alarms when finished.
Step 4: If a Network Connection is being made using
an INCOM twisted-pair connection to the 3-pin connector located on the top of the program­mer, refer to paragraph 2-2.2 for details on a
Network Connection.
Step 5: No matter which connection approach is used,
be certain that all plug-in connections are properly seated. This includes trip unit, exter­nal power and INCOM connections to the pro­grammer as well as connections from the pro­grammer to the trip unit or INCOM.
The programmer is now ready to have power applied.
3-3 POWER APPLICATION
Turn the programmer on by holding the red On/Off pushbutton in the depressed position for approximately one second. Upon release of the pushbutton, the first message will be displayed.
Three different types of messages can be displayed before the top level menu appears (Figure 2-9). The messages displayed will depend on the programmer connection or lack of a proper connection as follows:
• If the programmer detects the lack of a proper con­nection, two consecutive messages will be displayed. Figure 3-2 shows the first message displayed while the programmer searches for a compatible device. If the programmer is unable to make a connection, Figure 3-3 shows the second message that appears momentarily before the top level main menu is dis­played (Figure 2-9).

• If the programmer is connected to an INCOM Network, the message shown in Figure 3 - 2 will first be displayed followed by the INCOM message shown in Figure 3 - 4. The top level menu will then be displayed (Figure 2 - 9) .
• If the programmer is successful in its device search, the same in progress type message is displayed as shown in Figure 3-2. Refer to Figure 3-5 for a typical baud rate and address message momentarily dis­played once the trip unit is identified. The top level main menu is ultimately displayed and the program­mer is ready for use (Figure 2-9).
3-4 FUNCTION OVERVIEW
3-4.1 SELECT ADDRESS (SA)
The Select Address menu item is used when it is desired to communicate over the 3-pin INCOM connec­tion to an OPTIM trip unit. The address of the breaker you desire to communicate to is entered here. Note that an auxiliary power module must be plugged into the OPTIMizer for the OPTIMizer’s INCOM transceiver to work. Selectable addresses are in the range 001-FFE hexadecimal (001 to 4094 decimal).

3-4.2 FIND BAUD/ADDRESS (FI)
This menu item is used to retrieve the address and baud rate of the OPTIM trip unit connected to the OPTIMizer’s custom phone cord. The OPTIMizer executes this func­tion automatically when the OPTIMizer is first turned on. Several attempts will be made to retrieve the address and baud rate. If no trip unit is connected to the OPTIMizer at the time the OPTIMizer is turned on, an error message will be displayed.
3-4.3 FIND PRODUCT ID (ID)
The breaker frame type is displayed when this menu item is selected.
3-4.4 CHANGE BAUD/ADDR (BA)
The baud rate of the trip unit can be changed to that of the system by using this menu item. The baud rate is programmable to either 1200 or 9600 baud. All breakers connected together on a line must communicate at the same baud rate.
The address of a given breaker can be changed by using this menu item. Valid addresses of 001-FFE Hexadecimal (001 to 4094 decimal) can be used, how­ever, when OPTIM trip units are connected to a Breaker Interface Module (BIM) the range of usable addresses is from 1-32 hexadecimal (1-50 Decimal).
3-4.5 RATING PLUG (RP)
The rating plug installed in a trip unit can be read using this command.

The phase, neutral and ground currents are displayed in the Metered Values menu, as well as Total Energy, Forward Energy, Reverse Energy, Power, Peak Demand, Power factor, %THD of each phase, and Harmonic Content of each phase.
3-4.7 TEST MODE (TM)
Simulations of either a long delay, short delay, or instantaneous fault condition can be performed by using Test Mode. This can be done by first reading the setpoints and noting their adjustment. The trip mode menu item can then be selected and a current above the noted settings can be entered. A trip or no trip test can be performed. A test in progress may be terminated if the currents through the breaker under test are above 40% of the rating plug value. See section 3-9.

3-4.10 TRIP EVENT COUNT (TC)
The trip unit records the number of times that the trip unit has initiated a trip. This is displayed when the Trip Event Count is selected.
The trip unit can be adjusted for various time-current characteristic curves. This is done within the Setpoints
Menu. See section 3-7, and Figure 3-1. Notice: 1) Short Delay and Instantaneous Action can
not be turned off at the same time.
2) When long delay is set to I4t, the short delay slope must be set to Flat.

3-4.11 CAUSE OF TRIP (CT)
The OPTIMizer can display the cause of trip, similar to the cause of trip LEDs of the trip unit, but in some cases with more specific information. This information is available as long as the trip unit Reset pushbutton has not been pressed after a trip condition. For example, a non-compliant rating plug may cause an instantaneous trip to occur which will light the Instantaneous LED of the trip unit. However, the OPTIMizer in this case would display that the instantaneous trip is a result of a Bad Plug.

3-6 ASSIGN ADDRESS/SELECT BAUD RATE
The OPTIMizer Hand Held Programmer must be used to initially establish the baud rates and unique address­es of connected circuit breakers. Assigning or changing circuit breaker addresses and/or baud rates takes place within the same category of the main menu, Change Baud/Addr (BA). Each circuit breaker must have a unique address with all addresses containing three dig­its. The three digit address will be in a HEXADECIMAL Format with choices of 0 through 9 and A through F. The two baud rate choices are 1200 or 9600, displayed as 96B or 12B.
Notice: All circuit breakers are supplied from the facto-
ry with a 9600 baud rate “96B” and an address of “FFE” (Hex Form) already programmed. Keep in mind, however, when assigning addresses, the Breaker Interface Module will only recognize addresses at or below 32 HEX (two digits).
3-6.1 DIRECTLY CONNECTED BREAKER ADDRESS AND BAUD RATE
Use the following steps as a guide to assigning or changing addresses and selecting baud rates when the programmer is directly connected to a circuit breaker:

Step 5: Once the desired baud rate and address are
correctly displayed, hold Save p u s h b u t t o n depressed and depress Select p u s h b u t t o n. This simultaneous use of the two pushbuttons will enter the new baud rate and address. If the changes are accepted, the display will indicate the acceptance momentarily before returning to the main menu (Figure 3-15).
Notice: Keep in mind that a change in the baud rate
and/or address is password protected. Step 5 may require the entry of a valid password before any changes are accepted. If the pro­grammer was already turned on, and a valid
password was initially entered as described in paragraph 3-4 Method 1, entry of a password will not be required again and the baud rate and/or address changes will be saved. If a valid password was not initially entered, the display will require the entry of a valid pass­word before any changes can be saved (Figure 3-8). Follow the steps outlined in paragraph 3­4 Method 2 to enter a valid password.
Notice: Any time a circuit breaker address or baud rate
is changed, verify that the correct address and baud rate are displayed by using the Right- Arrow or Left Arrow p u s h b u t t o n s to move the blinking cursor in the main menu to Find Baud/Addr (FI). Use the Select pushbutton to enter Find Baud/Addr (FI), and the newly assigned address and selected baud rate will be displayed.

3-9 TEST TRIP UNIT
Digitrip OPTIM 550, 750 and 1050 Trip Units contain a test capability. One of the means for performing tests is through the use of the OPTIMizer Hand Held Program­mer. The intent is to permit the periodic performance of tests that verify the functional performance of the trip unit. Two types of testing are possible through the use of the OPTIMizer Hand Held Programmer, the “No-Trip” and the “Trip” tests.
No-Trip Test: This test can be performed using the internal battery power of the programmer. It verifies that the trip unit is performing under test within acceptable limits of the programmed protective setpoints.
Trip Test: This test can only be performed using exter­nal power supplied by an Auxiliary Power Module or by auxiliary power supplied to the circuit breaker. The addi­tional power is required to activate the breaker’s flux transfer shunt trip. This test verifies the trip unit’s perfor­mance, as well as the trip circuitry and mechanical oper­ation of the circuit breaker.
Notice: Keep in mind that an Auxiliary Power Module is
required to perform a “Trip” test. Refer to para­graph 2-2.2 for details on the use of an Auxiliary Power Module.
Notice: Basic protection functions are not affected dur-
ing the performance of testing procedures.
Proceed with the following steps to perform a “Trip” or a “No-Trip” test:
Step 1: With the programmer turned on and the main
menu displayed, use the Right-Arrow or Left- Arrow pushbuttons to move the blinking cursor to Test Mode (TM) (Figure 3-26).
Step 2: Use the Select pushbutton to enter the Test
Mode (TM). The blinking cursor indicates
which test category is active and able to be selected (Figure 3-27).
Step 3: Use the Right-Arrow or Left-Arrow pushbut-
tons, if required, to move the blinking cursor to a different test category. Use the Select push-
Effective 8/99
Page 22
I.B. 29C892B
button to choose a particular category, Phase for example, and the next selections are dis­played Trip or No Trip (Figure 3-28).
Step 4: Once again, use the Right-Arrow or Left-
Arrow pushbuttons, if required, to move to a
different test category. Use the Select push­button to choose a particular category, Trip for example, and two different notices are momen­tarily displayed before the next selection appears (Figures 3-29 and 3-30).
Step 5: After the two momentary displays, the test cur-
rent screen is displayed permitting the selec­tion of the desired test current (Figure 3-31).
Step 6: The blinking cursor indicates the selectable test
current field. The current initially displayed is the minimum test current value. Use the U p o r Down pushbuttons to alter the current value.
Step 7: Once all the test parameters have been select-
ed, hold Save pushbutton depressed and depress Select pushbutton to initiate the test. When the test is completed, a cause of trip message is displayed (Figure 3-32).
3-10.1 USING THE COPY COMMAND (CP)
Plug the OPTIMizer into the trip unit that the settings are to be copied from. Move the cursor to the main menu item CP. Press the Select key and wait while the OPTIMizer reads the trip unit’s setpoints. The message Accepted will be displayed if the copy was successfully completed. The settings are now stored within the OPTIMizer's memory and will be retained even after the OPTIMizer is turned off.
3-10.2 USING THE DOWNLOAD COMMAND (DL)
Plug the OPTIMizer into the trip unit that the stored settings are to be downloaded to. Enter the password for the OPTIMizer within the password main menu item PA. Move the cursor to the main menu item DL. Press the Select key and wait while the OPTIMizer gets the address of the trip unit and then downloads the OPTIMizer's stored settings to the trip unit. If the OPTIMizer’s password was not entered, the operator will be required to first enter their password and then reselect the Download menu item from the main menu. The message Accepted will be displayed if the settings were successfully downloaded.
Step 8: Use the Up-Arrow pushbutton to return to the
main menu.
Testing will not be permitted to proceed if there is greater than 0.4 per unit of current flowing on a phase circuit or 0.2 per unit of current on a ground circuit. The maximum permitted current value can be determined by multiplying the appropriate per unit value (0.4 or 0.2) times the ampere rating of the installed rating plug.
Notice: For currents less than the trip unit setpoint, no
message is displayed after the “Accepted Message.” The trip unit will not be placed in a Test Mode and, therefore, no pickup LEDs will flash. The trip unit, however, must be reset. The OPTIMizer will eventually return to the main menu.
3-10 COPY AND DOWNLOAD COMMANDS
The OPTIMizer can quickly download trip unit setpoints from one breaker to other breakers in a system. The per-unit values (not the current ampere values) are copied from one breaker and downloaded to any other breaker in the OPTIM family within a system. The set­tings are permanently retained in the memory of the OPTIMizer until another copy sequence replaces them.
Notice: The Copy /Download commands will not
change factory enabled functions such as ground fault trip or alarm. When copying from a trip unit with ground fault trip to a trip unit with ground fault alarm, only the pick-up, slope, and time adjustments are copied.
Some breakers such as the DS will have setting limita­tions based on the rating plug value. If settings are downloaded which are not within the allowable limits of the trip unit and rating plug, an error message will be displayed. See I.L. 29C891 Table 3.3 for allowable set­tings. This may also be the case for ground fault set­tings in breakers above 1200 amps.
3-11 RESET TRIP UNIT (RE)
The trip unit status indicators are generally reset by pressing the Reset pushbutton on the trip unit. In some instances, such as when a motor operator is used with on an OPTIM breaker, it may be desirable to use a remote reset. The reset trip feature is used in this case.

SECTION 4: TROUBLESHOOTING AND MAINTENANCE
4-1 LEVEL OF REPAIR
This manual is written based on the assumption that only unit-level troubleshooting will be performed. If the cause of a malfunction is traced to an OPTIMizer Hand Held Programmer, the device should be replaced. The malfunctioning programmer should be returned to Cutler-Hammer.
4-2 TROUBLESHOOTING
Refer to Table 4.1 for troubleshooting guidelines.
4-3 MAINTENANCE AND CARE
The OPTIMizer Hand Held Programmer is designed to be a self contained and maintenance free device, except for battery replacement. Refer to paragraph 2-
2.1 for battery information.
The OPTIMizer Hand Held Programmer should be stored in an environment that does not exceed the stor­age temperature range of -30°C to +85°C. The environ­ment should also be free of excess humidity. Store the device in its original packing material or the provided carrying case.
4-4 RETURN PROCEDURE
The Troubleshooting Guide (Table 4.1) is intended for service personnel to identify whether a problem being observed is external or internal to the device. If a prob­lem is determined to be internal, the device should be returned to the factory for replacement. To have an OPTIMizer returned, contact your local Cutler-Hammer authorized distributor.
