I.B. ATS-I005 Page 1 SECTION 1: INTRODUCTION 1.1 PRELIMINARY COMMENTS AND SAFETY PRECAUTIONS This technical document is intended to cover most aspects associated with the installation, application, operation and maintenance of the IQ Transfer. It is provided as a guide for authorized and qualified personnel only in the selection and application of the IQ Transfer. Please refer to the specific WARNING and CAUTION in Section 1.1.2 before proceeding.
I.B. ATS-I005 Page 2 An automatic transfer switch consists of three basic elements: that the switch operates properly through a series of programmed sensing and timing functions. 1.
I.B. ATS-I005 Page 3 the IQ Transfer display from function to function or step to step within a function. Three LEDs at the top of the faceplate provide an immediate indication as to the device’s operational mode. An integral Help Mode provides immediate user assistance in the form of English language message displays through the use of a front panel Help pushbutton.
I.B. ATS-I005 Page 4 Standard Feature: Time Delay Emergency to Normal (TDEN) TDEN delays the transfer to the Normal Source to permit stabilization of the Normal power source before the transfer is made. This timer will begin the countdown from its setting value when the Normal Source becomes available. During the countdown of this timer, if the Normal Source should become unavailable, the timer will be aborted.
I.B. ATS-I005 Optional Feature 5E: Overvoltage Monitoring for Source 2 (2OVD, 2OVP) This feature function the same as Optional Feature 26C, except for Source 2 instead of Source 1. Optional Feature 8C/8D: Transfer Time Delay Bypass This factory programmed feature allows an external pushbutton input to be used to bypass the timer for Standard Feature (TDNE) or Standard Feature (TDEN) individually, or both simultaneously.
Page 6 button re-transfer to Normal from the Emergency Source mode. If this option is not selected the factory default selection is automatic. Optional Feature 32A: Time Delay Neutral (TDN) This feature provides a time delay in the transfer switch Neutral position when both breakers are open. This delay takes place when the load is transferred in either direction to prevent excessive in-rush currents due to out-of-phase switching of large motor loads.
I.B. ATS-I005 SECTION 2: HARDWARE DESCRIPTION 2.1 GENERAL The purpose of this section is to familiarize the reader with IQ Transfer hardware, its nomenclature, and to list the unit’s specifications. The information presented is divided into the following four parts: • Operator Panel • Rear Access Area • External Hardware • Specification Summary 2.

I.B. ATS-I005 Page 11 SECTION 3: OPERATOR PANEL 3.1 GENERAL The operator panel, which is normally accessible from the outside of a panel or door, provides a means for being alerted to specific conditions, receiving functional help, programming, and parameter monitoring/selection (Figure 2-1).
I.B. ATS-I005 Page 12 Figure 3-1 Software and Options Identification Display Note: The entire Figure 3-1 message is shown for clarity, in actuality the message scrolls across the display as space permits. Status - Display LED This LED is lit red when action is occurring, such as a timer timing down, and one of the other display categories has not been selected. When the action is completed, the display goes blank and the LED turns off. The Status position is the default position of the display.
I.B. ATS-I005 Page 13 Upon test initiation, a generator start of the non-preferred source is engaged after TDES timeout. If a full test is programmed, a transfer with all programmed timers occurs. The test engine run timer will hold the load for the required timeout and the test is concluded with a re-transfer cycle. For an engine run only test, no transfer will occur and the engine will run for the programmed run time.

Figure 3-3 Typical Source 1 Display (Single Phase Line Voltage RMS - Source 1) 3.4.
I.B. ATS-I005 3.4.6 SETPOINTS DISPLAY This display indicates presently programmed setpoints. The setpoints can only be altered in the Program Mode. Keep it mind, if a feature was not originally ordered and programmed, it will not be displayed (Figure 3-5). Refer to Section 5 for details. 3.4.7 HELP DISPLAY This display presents moving English language messages, explanations and prompts to assist the operator while in any of the three operational modes.
I.B. ATS-I005 Page 16 SECTION 4: OPERATION 4.1 GENERAL This section specifically describes the operation and functional use of the IQ Transfer. It is divided into three main categories: • Automatic Mode • Test Mode • Programming Mode The practical use of and operation within each specific category will be discussed. In this section it is assumed that prior sections were reviewed and that the operator has a basic understanding of the hardware.
I.B. ATS-I005 Source should fail and the Normal Source is available, the IQ Transfer will initiate a transfer to the Normal Source. Bypass Timers A momentary closure on Pins 9 and 10 of Connector J4 will bypass the timer for TDNE and/or TDEN. Go To Neutral A maintained closed contact on Pins 11 and 12 of Connector J4 forces the controller to switch to the neutral position, thereby disconnecting the load from both sources.

Any operator associated with programming the IQ Transfer will quickly discover that IQ Transfer programming is just a matter of simple, repetitive steps. Because of the importance placed, however, on this function and its critical relationship to the systems proper functioning, Section 5 is dedicated to the Programming Mode. Refer to this section and Table 5.1 for details. showing available and connected sources.

I.B. ATS-I005 Page 22 SECTION 5: PROGRAMMING 5.1 INTRODUCTION NOTICE Although all IQ Transfer programmable features are addressed in this section, only those ordered by the customer and initially programmed at the factory will appear in the display for programming changes in the field. The IQ Transfer is fully programmable from the device’s faceplate or through the communications port. Users can reprogram setpoints as well as other parameters.

I.B. ATS-I005 Page 24 SECTION 6: TROUBLESHOOTING AND MAINTENANCE 6.1 LEVEL OF REPAIR This manual is written with the assumption that only transfer switch system troubleshooting will be performed. If the cause of malfunction is traced to an IQ Transfer, the unit should be replaced with a spare. The malfunctioning unit should then be returned to CutlerHammer for factory repairs.
I.B. ATS-I005 Page 25 Table 6.1 Troubleshooting Guide (continued) Symptom Probable Cause Possible Solution(s) Changed undervoltage or overvoltage or underfrequency or overfrequency dropout setpoint and the pickup setpoint changed also. Pickup upper or lower limit ranges are dependent upon dropout setpoints. To prevent misapplication, they are automatically adjusted when overlapping occurs. Source 1 or Source 2 is not available when it should be.
I.B. ATS-I005 Page 26 Table 6.1 Troubleshooting Guide (continued) Symptom Unit displays Lock-Out. Unit displays “S1 BRKR” Unit displays “S2 BRKR” Probable Cause Possible Solution(s) Circuit breaker tripped. Check for overload/short circuit condition. Maintenance Selector Switch in disable position. Check Maintenance Selector Switch. Lock-out circuit wiring problem. Check lock-out circuit wiring. Source 1 circuit breaker did not open when it was commanded to open.
I.B. ATS-I005 Page 27 Table 6.1 Troubleshooting Guide (continued) Symptom Unit fails to communicate over Load Sequencing subnetwork. Unit fails to communicate over IMPACC network. Probable Cause Possible Solution(s) Addressable Relay(s) set to incorrect address. Set Addressable Relay(s) address from 002 to 00B. Addressable Relay(s) set to incorrect baud rate. Set Addressable Relay(s) baud rate to 1200 baud (SW1 = ON). Addressable Relay(s) Watchdog and Relay Pulse features not disabled.
