Controllers rated 625…1250 A
Controllers that are rated 625…1250 A require common control for proper operation. Control power is connected to the product through terminal block CP1, at terminals 1 and 4. This single connection point feeds the control module, contactors, and fans. Control power must be supplied as 110/120V AC or 230/240V AC, 50/60 Hz only. A control power source of at least 800 VA is required. The control power requirements include the control module (75 VA), bypass contactors (526 VA max), and fan power (150 VA). Depending on the specific application, additional control circuit transformer VA capacity may be required. Units with a control power rating of 230/240V AC have an undervoltage relay installed. Units built prior to 2014 may have potentiometers on the undervoltage relay. If potentiometers are present, you must set them according to Figure 36. Units built later than 2014 may not have potentiometers, because the settings are programmed internally to the undervoltage relay and no adjustment is required.
This section covers some considerations
that you need to address, depending on your application. Protective Modules You should install a protective module (see Figure 65) containing MOVs (Metal Oxide Varistors) to protect the SMC Flex power components from electrical transients and/or electrical noise. You can install protective modules controllers rated from 200…600V to protect the power components from electrical transients. The protective modules clip voltage transients that are generated on the lines to prevent such surges from damaging the SCRs. The use of MOVs is highly recommended, because 480V and 600V MOVs offer maximum protection of 1400V and 1600V, respectively.
There are two general situations that may occur that could indicate the need for using the protective modules. 1. Transient Spikes — Transient spikes will typically occur on the lines feeding the SMC Flex controller or feeding the load from the SMC Flex controller. Transient spikes are created on the line when devices are attached with current- carrying inductances that are open-circuited. The energy stored in the magnetic field is released when the contacts open the circuit. Examples of these include lightly loaded motors, transformers, solenoids, full voltage starters, and electromechanical brakes. Lightning can also cause spikes. 2. Fast-rising Wavefronts — If the SMC Flex controller is installed on a system that has fast-rising wavefronts present, although not necessarily high peak voltages, protective modules may be needed. Lightning can also cause this type of response. Additionally, if the controller is on the same bus as other SCR devices (such as AC/DC drives, induction heating equipment, or welding equipment), the firing of the SCRs in those devices can cause noise.
