QUICK START GUIDE

	Quick Start
General	This quickstart guide provides the information necessary for the operator to set the
	starter for basic operation. This manual should be read in its entirety before the
	starter is put into service.

• Connect the incoming power connections to terminals L1, L2 and L3.

• Connect the motor leads to T1, T2, and T3.

• Connect the control wiring to TB1 on the control card, as shown in the following diagram. USE ONLY THE START/STOP BUTTONS OR THE EXTERNAL AUTO CONTROL.

•Turn on the power to the starter. The display should show the software release number and then rdy. If not, refer to the starter diagnostics beginning on page 38.

•See the programming chapter beginning on page 20 for a complete description of programming procedures and parameter descriptions. The important parameters to program are P1, P2, P3, P4, and P6.

•Provide a short Start/Stop sequence to the starter to check motor rotation. If the motor rotates backwards, swap any two power leads.

•Give a Start command and allow the motor to accelerate to speed.

•If the motor doesn’t begin accelerating immediately, increase parameter P4. If it takes off too quickly, decrease P4.

•If the motor takes too long to accelerate, decrease P6. If the motor accelerates too quickly, increase P6.

1. INTRODUCTION

1.2		Product Description
General Information	The RediStart Digital motor starter is a microprocessor-controlled starter for single or
	three-phase induction motors. The starter can be custom designed for specific
	applications.
	The starter offers:
	•	Solid state design.
	• Current limited reduced voltage starting.
	• Closed-loop motor current control.
	•	Programmable motor protection.
	•	Programmable operating parameters.
	•	Programmable metering.
	Available in NEMA (National Electrical Manufacturers Association) specified frame
	sizes, the starter may be used in numerous industrial applications. Each starter can
	operate within applied voltage and frequency values of 100VAC to 600VAC (optional
	1000VAC) and 23 to 75Hz. This feature enables the RDB6 to be installed in a wide
	range of sites and countries.
	The starter can be programmed for any motor FLA and all of the common motor
	service factors. It enables operators to control both motor acceleration and
	deceleration. It also protects the motor and its load from damage that could be caused
	by incorrect phase order wiring.
	The starter continually monitors the amount of current being delivered to the motor.
	This protects the motor from overheating or drawing excess current. The starter will
	automatically stop the motor if the line-to-line current is not within acceptable ranges
	or if the current is lost in a line.
Features	The enhanced engineering features of the starter include:
	•	Multiple frame sizes.
	•	Universal voltage operation.
	•	Universal frequency operation.
	• Programmable motor overload multiplier.
	• Controlled acceleration and deceleration.
	•	Phase rotation protection.
	•	Regulated current control.
	• Electronic motor thermal overload protection.
	• Electronic over/under current protection.
	•	Single phase protection.
	• Line-to-line current imbalance protection.
	•	Stalled motor protection.
	•	Programmable metering.
	•	Passcode protection.

	optional door mounted display) displays:
	•	Status information.
	•	Operating parameters.
	•	Fault codes.
	•	Thermal Overload Content.
	•	Motor current.
	• Motor current imbalance percentage.

2.3	Storage
General	If the starter is to be stored for a significant period of time before being installed,
	certain storage environmental conditions must be maintained.
	NOTE: The suggested maximum storage length is two years.
Environmental Conditions	To protect the starter during the storage period the following environmental
	conditions must be maintained:

• -40 degrees Fahrenheit to 158 degrees Fahrenheit (-40 degrees Centigrade to 70 degrees Centigrade).

• 20% to 95% relative humidity (non-condensing).

2.7			Standard and Heavy Duty Horsepower Ratings
General	There are 15 different RDB chassis sizes. Each frame size has two different
	horsepower ratings depending on the application.
Standard Duty Rating	The standard duty horsepower rating is for normal motor starting. The standard duty
	rating is a motor current that is 350% (3.5 times) of the full-load current for 30
	seconds. The standard duty rating table lists the maximum size of motor that can be
	started by each RDB unit.

3. INSTALLATION

3.1	Site Preparation
General Information	Before the starter can be installed, the installation site must be prepared. The
	customer is responsible for:
	• Providing the correct power source.
	• Selecting the control mechanism.
	• Obtaining the connection cables.
	• Ensuring the installation site meets all environmental specifications for the
	enclosure NEMA rating.
	• Installing the motor.
Connection Cables	The connection cables for the starter must have the correct current NEC/CSA rating
	for the unit being installed. Depending upon the model, the connection cables can
	range from a single #14 AWG conductor to four 750 MCM cables.
Site Requirements	The installation site must adhere to the applicable starter NEMA/CEMA rating. For
	optimal performance, the installation site must meet the following specifications:
	• Temperature: 32 degrees Fahrenheit to 104 degrees Fahrenheit (0 degrees
	Centigrade to 40 degrees Centigrade).
	• Humidity: 20% to 95% non-condensing.
	• Airways: Clearances are provided around all heat sinks.
	• Altitude: Less than 3300 feet (1000 meters) above sea level.
	NOTE: At altitudes greater than 3300 feet (1000 meters) above sea level, the starter
	size must be derated 1% for every 330 feet (100 meters) above this level.
Mounting	The starter must be mounted so the heat sink fins are vertically oriented in an area
	that does not experience excessive shock or vibration. All models require airway
	passages around the heat sink. During normal operation the heat sink may reach 194
	degrees Fahrenheit (90 degrees Centigrade). Do not install the starter in direct
	contact with any materials that cannot withstand these temperatures.

3.2	EMC Installation guidelines
General	In order to help our customers comply with European electromagnetic compatability
	standards, Benshaw Inc. has developed the following guidelines.
	Attention: This product has been designed for Class A equipment. Use of the product
	in domestic environments may cause radio interference, in which case the installer
	may need to use additional mitigation methods.
Enclosure	Install the product in a grounded metal enclosure.
Grounding	Connect a grounding conductor to the screw or terminal provided as standard on each
	controller. Refer to layout/power wiring schematic for grounding provision location.
Wiring	Wire in an industrial application can be divided into three groups: power control and
	signal. The following recommendations for physical separation between these groups
	are provided to reduce the coupling effect;
	• Different wire groups should cross at 90 degrees inside an enclosure.
	• Minimum spacing between different wiring groups in the same tray should be
	six inches.
	• Wire runs outside an enclosure should be run in conduit or have shielding/armor
	with equivalent attenuation.
	• Different wire groups should be run in separate conduits.
	• Minimum spacing between conduits containing different wire groups should be
	three inches (8cm).
Filtering	To comply with Conducted Voltage Limits a 0.33 uF L-G capacitor should be
	connected to each line at point nearest to the incoming power.
