Chapter 3. Installing the CS7000 Controller

Meeting the AC Input Power Requirements

For proper operation, the controller must be connected to a stable power source. The supply source should be capable of delivering at least 1.5 kVA per channel at 220V for 177 Series tools. For the 277 Series tools, at least 2KVA per channel is recommended.

The voltage tolerance for 220V controllers is 208 to 250 VAC.

NOTE:

?

CAUTION!

i

The maximum no-load speed of a nutrunner is based on a nominal AC input voltage of 220V depending on the type of controller; if the actual input voltage is lower, the maximum no load speed of the nutrunner will be lower than specified.

Failure to provide the proper power source can cause the following problems in your CS7000 Fastening System:

The nutrunner might shut down before it reaches the target torque during a rundown cycle.

The nutrunner might not operate when a cycle-on signal is applied to the system.

The maximum free speed of the nutrunner might be lower than specified.

Input Power Protection

A circuit breaker or fuses positioned between the AC input and the servo amplifier provides the controller with short circuit protection.
