If a prohibitive overload or short circuit failure occurs at the RIP output during
operation then the RIP enters the mode of short-time operating with pauses of 15 to 60 s
until the malfunction is repaired. The TROUBLE indicator pulses twice per second while the
buzzer issues two beeps with 1.5 s between them. The RIP automatically recovers its
operability after eliminating the overload or short circuit failure within 60 seconds max.
Indicator’s and buzzer’s performance for various RIP conditions are shown in Table 2.

“OFF/3 s
”: Turns off for a short time every 3 s;
“ON 10 s
”: Turns on for a short time within 10 s.
