Okuma Alarm-C 3730 Coolant flow
Coolant flow was suspended longer than the monitor time.
Code
None->The coolant flow sensor did not turn ON within the coolant flow monitor time (for coolant supply sensor types).
1->When a flow of coolant1 was watched, even though the watching time which was set on a parameter was exceeded, 1st coolant1 or 2nd coolant1 did not flow.
2->When a flow of coolant2 was watched, even though the watching time which was set on a parameter was exceeded, 1st coolant2 or 2nd coolant2 did not flow.
3->When a flow of coolant3 was watched, even though the watching time which was set on a parameter was exceeded, 1st coolant3 or 2nd coolant3 did not flow.
4->Coolant flow 4 did not flow beyond fixed time at the time of coolant 4 output ON.
5->When a flow of coolant1 was watched and 1st coolant1/2nd coolant1 output condition was OFF, A flow switch turned it on over the time which was set on a parameter.
6->When a flow of coolant2 was watched and 1st coolant2/2nd coolant2 output condition was OFF, A flow switch turned it on over the time which was set on a parameter.
7->When a flow of coolant3 was watched and 1st coolant3/2nd coolant3 output condition was OFF, A flow switch turned it on over the time which was set on a parameter.
8->Oil mist flow sensor for A turret did not turn ON within the flow monitor time.
9->Oil mist flow sensor for A turret did not turn ON within the flow monitor time.
10->A Turret coolant flow sensor did not turn ON within the coolant flow monitor time.
11->B Turret coolant flow sensor did not turn ON within the coolant flow monitor time.
12->High pressure coolant flow sensor did not turn ON within the coolant flow monitor time.
13->2nd coolant flow 1 did not flow beyond fixed time at the time of 2nd coolant 1 output ON.
14->2nd coolant flow 2 did not flow beyond fixed time at the time of 2nd coolant 2 output ON.
15->2nd coolant flow 3 did not flow beyond fixed time at the time of 2nd coolant 3 output ON.
16->Coolant flow 5 did not flow beyond fixed time at the time of coolant 5 output ON.
17->Coolant flow 1(L-tool)/coolant flow 3 did not flow beyond fixed time at the time of coolant 1(L-tool)/coolant 3 output ON.
18->Coolant flow 1(M-tool)/coolant flow 6 did not flow beyond fixed time at the time of coolant 1(M-tool)/coolant 6 output ON.
19->Turret upper side coolant flow sensor did not turn ON within the coolant flow monitor time.
20->Turret lower side coolant flow sensor did not turn ON within the coolant flow monitor time.
21->Chip coolant flow sensor did not turn ON within the coolant flow monitor time.
22->When a flow of coolant1(L-tool)/3 was watched, even though the watching time which was set on a parameter was exceeded, 1st coolant1(L-tool) did not flow.
23->When a flow of coolant1(M-tool)/6 was watched, even though the watching time which was set on a parameter was exceeded, M-tool coolant did not flow.
24->When a flow of coolant7 was watched, even though the watching time which was set on a parameter was exceeded, 1st coolant7 did not flow.
Probable Faulty Locations
1) A low coolant level or clogged coolant pipe
2) Wrong supply sensor switch position
3) A faulty supply sensor
Measures to Take
1) Supply coolant or change the coolant pipe with a new one.
2) Check the coolant discharge confirmation switch.
3) Change the coolant discharge confirmation switch with a new one.
