Electronic Timers are used to maintain the Lubrication cycle in automatic single shot Lubrication Units. It is basically ON - OFF timer with following technical specification.
Power Supply : : | 220 V AC + - 10%, 50 Hz |
---|---|
Operating Temperature : : | 0-55° C. |
Maximum Power Consumption : : | 2.0 VA |
Control Action : : | On Off Type. |
OutPut : : | 220 V AC |
Start : : | Automatic On output when power is turned On |
Application : : | provides On - Off action of Lubricator Motor |
Model | ON TIME : | OFF TIME : | SETTING OF TIME : | PRESENCE OF SWITCH FOR LUB SHOT : |
---|---|---|---|---|
ET-5 | 5 seconds fixed | 1-128 minutes | By Knob | Yes |
Electronic Controller can also be used to ON-OFF the Motorised units. This device maintain the lubrication cycle as well as monitors the operation of float Switch and Pressure switch at the same time. Electronic Controllers are suitable for units such as : LAU-03FPS, LAU-05 FPS, LAU-08 FPS & LDU-03 FPS However, cintactor is to be used in this case.
Fault relay contacts can also be used for audio / Visual commands or for interlocking the machine in case of lubrication falure.
In case arrangement for contactor is not possible, ECC-5 can be used. It is a complete solution with in built controller and contactor.
Power Supply : | 220V +- 10% AC, 50Hz |
---|---|
Motor Relay on Time : | 5 seconds after actuation of pressure switch |
Limitation of motor relay On time : | 60 seconds in case of pressure failure |
Off Time : | Selectable 1-128 minutes |
Off Time Setting : | By Knob |
Start : | Motor Relay On when power is turned On. |
Reset : | by Pushing the Button Rest. |
Repeat Accuracy : | +- 10% |
Operating Temperature : | 0-55°C |
Maximum Power Consumption : | 3 VA |
Contact Rating : | (a) Motor Relay : One potential free NO contact 2 amp non indicative at 220V AC (b) Fault Relay : One potential free change contact 2 amp non indicative at 220V AC |
Lub Shot Facility : | Alub shot switch parallel to relay contacts provides extra lubrication as and when required. |
Monitoring of Oil Pressure : | LED Lub fault flickers & fault relay is actuated in case pump fails to develop pressure even in 60 seconds. |
Monitoring of Oil Level : | LED Low OIL Flickers when oil level in the reservoir goes below the Float Switch. |
