Page 9: Chapter 3: Motor Overload Protection
3.1 Thermal Overload Relay The XLS Series provides motor overload protection using an adjustable solid state overload relay. The standard XLS Series is furnished with a Class 10 overload, providing an overload rated at 600% current for 10 seconds. Class 20 overload relays, providing an overload rated at 600% current for 20 seconds, are also available. -
Page 10: Chapter 4: Connections
Note: Some units may have the overload on the load side of the starter. XLS Series Unit Power Connections 4.1.1 Grounding Connect the ground cable to the ground terminal as labeled on the unit. Refer to the National Electrical Code for the proper ground wire sizing and be sure that the ground connector is connected to earth ground. - Page 11 4.2.5 Relay Contacts All the relay contacts are FORM C common (N.O., N.C.), except the optical triac output. Motortronics recommends fusing all contacts with external fuses. TB2 is the terminal block for all external contacts. Each contact is explained in the following sections. See Chapter 9 for main control board layout.
- Page 12 XLS Series Solid State Soft Starter 39 - 1250A 4.2.6 Programmable Relay The XLS includes a programmable relay on TB2 which is located on the main control board. The relay is rated for 240 VAC, 5 A and 1200 VA. The relay responds to either a fault condition or an up-to-speed condition.

J7. Refer the Chapter 9 for the main control board layout. Note the type of color coding of the wires connected to J5, J6 and J7. Motortronics uses two possible configurations. Both configurations have 4 wires going to each plug. The first configuration consists of 4 wires color coded black, yellow, grey and white. -
Page 21: Replacing Scr Devices
Solid State Soft Starter 39 - 1250A 8.3 Replacing SCR Devices Two types of SCRs are used in the XLS Series depending on the horsepower/amperage rating of the unit. Isolated SCRs are used in smaller units and “hockey puck” type SCRs are used in larger units. - Page 22 Failure to remove both line and control power before starting this procedure may cause personal injury or death. • Motortronics uses two types of clamps with gauges for reading the amount of force on the device. The first type of force gauge uses a spin washer.
- Page 23 XLS Series Solid State Soft Starter 39 - 1250A washer gauge, verify that the washer spins freely after clamping. Once proper force is reached make sure that the SCR pucks are securely held between the heatsinks and aligned evenly. • Replace any lugs, MOVs, snubbers, power straps, printed circuit boards and associated wiring that was removed in step 4.
