Chapter 1: Getting Started

1-2 Chapter 1: Introduction

Brushless DC impeller-style blowers offer multispeed aerodynamic perform-ances for all types of high-airflow applications. AMETEK standard designscome with fully integrated electronics and are available in various input volt-ages.

The RTP1300 Blower with Mounting Bracket Assembly has an operating volt-age of 27.6 VDC and a CFM of 237. It has two main components: a blowerand a 27.6 VDC motor.

This manual provides step-by-step instructions and annotated diagrams forservicing the RTP1300 Blower with Mounting Bracket Assembly. A parts listfor the blower is provided in appendix A.

On the parts lists, each part is identified by part number, item number, quan-tity and description. The item numbers are used to annotate the schematicdiagrams included in this manual (see, for example, figure 4.1 (p. 4-3).Circled numbers on the diagrams refer to the item numbers in the applicableparts list. For example:

2-2 Chapter 2: Recommended Maintenance

The primary advantage to using brushless DC impeller-style blowers is thelife-cycle cost savings with regard to maintenance. Should the motor fail, itmust be replaced as a unit. It cannot be disassembled and nonworking partsreplaced. All other parts that comprise the RTP1300 Blower with MountingBracket Assembly can be removed and replaced as needed.

INTRODUCTION

Chapter 3: Troubleshooting

3-2 Chapter 3: Troubleshooting

When using the RTP1300 Blower with Mounting Bracket Assembly, you mayencounter one or more of the following problems:

• Locked impeller

• Over temperature shutdown (internal temperature greater than 110_ C)

• Under voltage shutdown (less than 11.0 VDC)

The sections below tell you how to troubleshoot, find the cause of the prob-lem you are experiencing and fix the problem.

If the impeller is not rotating and appears to be locked, refer to the followingsections to determine whether the motor has failed or an obstruction hasimpeded movement of the impeller.

If the motor is not operating, follow the steps below to determine the cause:

1. Incorrect Voltage Connections. Check the connections to the motorterminals to verify that the motor leads are connected to the proper sup-ply voltage according to the hookup settings shown in table 3.1 (p. 3-2).

Table 3.1. Blower Hookupwith 27.6 VDC Motor

Operation Red (+) Yellow Orange

High Speed + 27.6 VDC Open Open

Med Speed + 27.6 VDC + 27.6 VDC Open

Med/Low Speed + 27.6 VDC Open + 27.6 VDC

Low Speed + 27.6 VDC + 27.6 VDC + 27.6 VDC

If the leads are reversed, the unit will not operate. A reversed connectionwill short the power source. Check the polarity of the connection to thebus wiring.

The series-protection device allows power to be supplied by the closureof a “fast-acting” contactor, relay or similar device to ensure that theblower will start. AMETEK recommends the use of a series fuse or afast-acting circuit breaker large enough to protect the wiring andelectronics of the device needing circuit/fuse protection.

NOTE

INTRODUCTION

LOCKED IMPELLER

Motor Not Operating

Chapter 3: Troubleshooting 3-3

Correct the voltage-connection error. Normal blower operation shouldbegin when the connection error has been corrected and the protectiondevice reset.

2. Improper Voltage. Check the motor connections with a voltmeter toverify that the proper voltage is being supplied to the motor.

3. Faulty Motor. If the motor is receiving the proper voltage and still doesnot operate, the problem likely is with the motor. Replace the motor, andtry the blower again.

If an obstruction is impeding the rotation of the impeller, disassemble theblower (see chapter 4), and attempt to clear the obstruction. After the obstruc-tion has been cleared, try the blower again.

The blower may be malfunctioning because it has overheated. This meansthat the blower’s internal temperature is greater than 110_ C, the temperatureat which the blower’s internal thermostat is set. Normal operating tempera-ture ranges from -40_ C to 70_ C (see figure 3.1, p. 3-4). Normal operationshould resume when the blower’s internal temperature drops to within therange for normal functioning.

The blower may be malfunctioning because the voltage supplied is less than11.0 VDC, which is the absolute minimum voltage required for normal opera-tion. Optimal voltage is 27.6 VDC. Intermittent voltage should be in the rangeof 18 VDC to 32 VDC.

Check the motor connections with a voltmeter to verify that the proper volt-age is being supplied to the motor. Adjust the voltage as needed, and try theblower again. If the motor is receiving the proper voltage and still does notoperate, the problem likely is with the motor. Replace the motor, and try theblower again.
