• A four line, 20 character LCD has a backlit display which enables easy viewing under all conditions (see Asco 7000 Brochure below for screen shots).
• All screens can be navigated using only six buttons.
• Touch pad programming of features and settings without the need for meters or variable power supplies.
• On-board diagnostics provide control panel and ATS status information to analyze system performance.
• Displays and counts down active timing functions.
• Selectable multi-language display (English, German, Portuguese, Spanish, or French).
• Password protection to prevent unauthorized tampering of settings.
• For more detailed information, see 7000 Series Microprocessor Controller.

Asco Series 7000 User Interface

• Manual transfer control switch for transferring load from normal to emergency, and back again.
• Switch position indicating lights (16 mm, industrial grade LEDs).
• Source acceptability indicating lights with true indication of the acceptability of each source, as determined by the voltage, frequency, voltage unbalance, and phase sequence settings of the control panel (16mm, industrial grade LEDs).
• See diagram in the pictures above for layout.

• Accessory 1PS1 – Extended control power ride-through (approx. 25 seconds) for Group 5 ATS controller and select communications and metering accessories including 72EE2 and 135L.

Indicators

• Accessory 14A/14B – Additional auxiliary contact sets to indicate switch position. Two sets are standard. Specify total number of sets if more are required.
• Accessory 18B – Two-pole, double-throw contacts operate when emergency source voltage is present at transfer switch terminals.
• Accessory 18G – Two-pole, double-throw contacts operate when normal source voltage is present at transfer switch terminals.
• Accessory 99 – “Push-to-Test” feature on all pilot light indicators.

Customer Control Circuits

• Accessory 30A – Load-shedding circuit initiated by opening of a customer-supplied contact.
• Accessory 30B – Load-shedding circuit initiated by removal of customer-supplied control voltage. (Specify voltage).
• Accessory 31Z – Selective load disconnect control contacts (two provided) which operate with time delay prior to and/or after load transfer and retransfer.
• Accessory 43R – Terminal block for all customer control connections on 30-150 amp only (standard on all other sizes).

Extension Harness
