The system comprises of an IP65 rated enclosure containing an ATEX approved oil separator alarm, solar panel, battery, and monitoring electronics mounted on an angled galvanized steel pole and flange assembly with an integral 10m sensor cable which may be extended to a maximum of 300m. An optional wall mounting bracket is also available. A specially designed fail-safe solid-state sensor is mounted at the required level in the separator chamber.A high intensity flashing beacon on the top of the enclosure warns that the separator requires emptying, or of sensor fault (short/open circuit) conditions. An integral solar panel trickle-charges the heavy-duty lead-acid 18AH battery. A Test/Reset button is provided to check operation by simulating an alarm condition.To conserve battery power, the SOL 3000 is active for 20 seconds every 60 minutes or as required (factory option).If an alarm condition is present, the high intensity beacon will flash until the alarm condition is cleared.There is sufficient battery capacity for the beacon to operate for 7 days in poor light conditions.
