The HG1 Series is a repeat cycle, two circuit timer. It has a separate dial scale for "ON" and "OFF" time. Both "ON" and "OFF" time intervals are individually adjustable by concentric knobs on the front of the unit. The combination of the "ON" plus the "OFF" time equals the total time cycle of the unit.
The timing range is 120 seconds in one second increments, with an accuracy of ± 0.5 seconds. The operating temperature range is -20ºF - 140ºF (-29ºC - 60ºC).
The timer has two 4-digit pushbutton switches to provide exact setting of the "ON" and "OFF" time setpoints. Two led indicators to show "ON" and "OFF" time operation. The setting accuracy of the timer is 0.01% of the setting, or 35 ms, whichever is larger. Reset time is 35 ms. Operating temperature is 32ºF - 122ºF (0ºC - 50ºC). Power on response time is 35 ms. The repeat accuracy of the timer is 0.01% of the setting, or 35 ms, whichever is larger. The timing range is 99 minutes: 99 seconds in 1 second increments.
24 VDC electromagnet available in two styles; hollow core to fit over the valve cap, and solid core to be placed next to the swinging bucket. Power supplies are available in 115 volt or 230 volt configurations. Available in combinations or individually.
