1-3 PRODUCT OVERVIEW

The OPTIMizer Hand Held Programmer is required for all OPTIM Trip Unit Systems. It plugs into the front of OPTIM 550, 750 or 1050 Trip Units and is powered by a standard nine volt battery (Figure 1-1) or auxiliary power module. The OPTIMizer accesses, displays, and configures information from OPTIM Trip Units. The OPTIMizer Hand Held Programmer provides a broad range of programming possibilities available with the OPTIM Trip Unit System and the range of compatible circuit breakers.

1-4 FEATURES AND FUNCTIONS

An OPTIMizer must be used to configure the trip unit for communications on the INCOM Network. This requires an operator, during initial start-up, to:

• Assign Unique Device Addresses

• Select Baud Rates

In addition, the OPTIMizer can be used to:

• Configure OPTIM Trip Unit

- Select frequency (50/60 Hz)

- Set security passwords

- Change time-current setpoints

- Select protection options

- Select High Load Alarm level

• Display Information

- Breaker description

- Time-current setpoints

- Metered values

- Trip event information

• Test OPTIM Trip Unit Performance

- Phase and ground

- Trip or no trip

• Communicate over INCOM

• Copy Trip Unit Settings

- To download to any OPTIM breaker of any type

SECTION 2: HARDWARE DESCRIPTION

2-1 GENERAL

The purpose of this section is to familiarize the reader with OPTIMizer hardware, its nomenclature, and any applicable specifications. The information presented is divided into the following three sections:

• Package and External Connections

• Operator Panel

• Specification Summary

Notice: Integral to the OPTIMizer Hand Held Program-

mer is the ability to lock out changes to a breaker’s settings through the use of a password. The correct password must be entered to proceed with setpoint changes, baud rate changes or the initiation of a test. The password entry field contains four digits that can be changed. The factory installed password 1000 can be used until a new password is selected by the user.

CAUTION

THIS IS A SOPHISTICATED PIECE OF ELECTRICAL EQUIPMENT. AS SUCH, IT SHOULD BE HANDLED CAREFULLY AT ALL TIMES TO AVOID POSSIBLE DEVICE DAMAGE.

2-2 PACKAGE AND EXTERNAL CONNECTIONS

The OPTIMizer Hand Held Programmer is packaged in a high strength plastic housing with approximate dimensions of 5.75 inches by 3.5 inches by 1.25 inches. An operator panel with a display and associated pushbuttons are located on the front of the device (Figure 2-1). External connections are made on the top of the hand held programmer (Figure 2-2). A top hinged protective cover is provided to protect external connections from the entrance of foreign matter. The protective cover is opened through the use of a thumb nail notch (Figure 2-

3). A storage case holds the hand held programmer and its phone type connection cord.

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

Page 5

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.
