Installation Instructions

The units feature two isolated sets of contacts that are ideal for use with two control circuits with different voltages.

The unique microcontroller-based voltage and phase-sensing circuit constantly monitors the voltages to detect harmful power line conditions. When a harmful condition is detected, the MotorSaver's output relays are deactivated after a specified trip delay. The output relays reactivate after power line conditions return to an acceptable level and a specified amount of time has elapsed (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.

SSAC Timers

The TDR Series of time delay relays are comprised of digital circuitry and a 10 A isolated relay output. The ON and OFF delays are selected by means of two ten position binary switches, which allow the setting of the desired delay the first time and every time. Upon application of input voltage, the green LED glows, the output relay is energized, the red LED glows and the T1, ON time begins.

IDEC E-Stops

Improper Installation or excessive force to the stop button in an emergency may break or dislodge a vital part, causing the spring loaded contact to stay closed. This situation renders the E-Stop incapable of stopping the machine and can lead to catastrophic events, personal injury and possible loss of life. The XA and XW series of Emergency Stop switches include a revolutionary new technology called
