MIDO Oil protecttorelay MDC303M/305M
MDC303M
⊙ Characteristic
. 1 stage
. Sequential control by microprocessor
. Adopting double safety circuit so that the system is not to be operated
when there is an abnormal signal on the flame detection circuit
. Safety system operates when a fire is not ignited or a fire goes out
suddenly
. When fire goes out in normal operation condition, the burner is re-
ignited once
. In preparation of fire extinction, manually reset is operated
⊙ Nominal
. Nominal voltage : AC 110/220V 50/60㎐ 1phase
. Ambient temperature : -20℃ ～ 60℃
. Ambient air density : 35% ～ 85% (however, while not frozen)
. Power capacity : AC250V 5A
. Power consumption : less than max 7W , AC 30mA
⊙ Time
. Pre purge time : 14s ± 2s
. Pre ignition time : 9s ± 2s
. Post ignition time : 7s ± 2s
. Safety switch : 7s ± 2s
. Delay in extinction detection : less than 1sec
⊙ CDS sensitivity
. Ignition detection : < 47㏀ ± 10 ㏀
. Fire extinguishing detection :> 82㏀ ± 10 ㏀
. False flame :< 10㏀ ± 5 ㏀
