[. . . ] DO NOT apply power to the photo sensor inputs. Time Switch Specifications CLOCK VOLTAGE: 120, 240, 277 volt A. C. SET POINTS: ("On" or "Off"): 28 Total BATTERY POWERED CARRYOVER: 24 hours. (1. 32 Kg) CASE: Drawn steel, ; 7 3/4" (19. 7 cm) high, 5" (12. 7cm) wide, 3" (7. 6 cm) deep; gray finish w/lockable spring hasp. KNOCKOUTS: Combination 1/2-3/4" (one on back and each side, two on bottom) FULL ONE YEAR WARRANTY If within one (1) year from the date of purchase, this product fails due to a defect in material or workmanship, Intermatic Incorporated will replace or repair it free of charge. [. . . ] The surge suppressor selected must be of the same voltage as the load (contactor or relay coil) being controlled. Use Intermatic part number as follows: 176ET8A for 24 volt nominal loads - marked 8A 176ET9A for 120 volt nominal loads - marked 9A 176ET10A for 240 volt nominal loads - marked 10A 176ET22A for 277 volt nominal loads - marked 22A Where excessive electrical noise is generated elsewhere in the load circuit an isolation relay may be required in addition to the surge suppressor or additional surge suppressors may be required on external contacts. Insert load wire under one side of pressure plate and insert surge suppressor lead under other side of pressure plate. Be certain that the body of the surge suppressor is at least 1/2 inch from the timer switch case. Insert surge suppressor(s) across each contact switching an inductive load. Do not use surge suppressors on both the normally open and normally closed side of the same output relay. TIMER POWER PHOTO SENSOR CONNECTION BASIC DIAGRAM DOOR LABEL ET716CK General Information (See Fig. 3) Mounting Holes MODE SELECTOR switch has four settings: "MAN" -The automatic operation is bypassed while in this position. Load(s) can be manually switched "ON" or "OFF". * "AUTO"-Normal position for automatic operation. The timer will resume automatic operation beginning with the next set point. * "SET"-To set or modify the clock, and program. "REVIEW"-To check the program, or clear entries for Knockouts program modification. ON INDICATOR LIGHT:* Flashes when the selector switch is set in "REVIEW" or "SET". Glows steadily when normally "open" contacts are "closed" during automatic or manual operation. Does not glow when normally "open" contacts are "open" during automatic or manual operation. RESET BUTTON: Resets the microprocessor before programming or to erase the entire program. CLEAR BUTTON: Clears the displayed entry in "SET" or "REVIEW". ON AND OFF BUTTONS:* To enter programming steps for "ON/OFF" set points as well as manually controlling the loads. *NOTE: If the photo sensor has been connected the load will not switch ON unless darkness is sensed. To check the wiring, temporarily disconnect the photo sensor from the time switch. This will allow the load to be switched ON, regardless of the ambient light level, by pressing the ON keypad in either MAN or AUTO modes. A built in time delay may cause up to a 2 minute response delay to sudden changes at Photo Sensor input. -2- Programming Steps WARNING: DO NOT PRESS RESET BUTTON WHILE PROGRAMMING OR THE ENTIRE PROGRAM WILL BE LOST. For example, if the time is 8:00 AM press 800 and press "AM". [. . . ] NOTE: When in automatic operation, if the "ON" or "OFF" buttons are pressed, the loads will activate accordingly. Discharged or faulty batteries may drain unit of power even with power on. Press recessed RESET button with pen or pencil and hold for two seconds. While pressing: ON indicator light will be lit and display will show a colon. [. . . ]
