- Page 16 Technical Information PCB Relay For UCV Component Description The PCB relay for the snorkel is a micro-processor based control. Simply stated, the control uses a CPU (central processing unit) to detect Switch status and to apply the appropriate polarity (negative or positive) To the DC motor to run the snorkel in the down or up position respectively.

Primary (120 V.A.C.) Secondary (24 V.D.C.) Motor Step-down Transformer The motor step-down transformer steps down 120 V.A.C. to 24 V.A.C. The 24 V.A.C. are rectified to 24 V.D.C. to run the motor. Page 20... -
Page 23: Up Limit Switch
Up Limit Switch Interference Switch Up Limit Switch The Up Limit Switch is a (S.P.S.T.) normally open switch. When the snorkel reaches the upper position, the switch closes a circuit which stops the motor. Page 21... -
Page 24: Down Limit Switch
Down limit switch Down Limit Switch The Down Limit Switch is a (S.P.S.T.) nomrally open switch. When the snorkel reaches the lowest position, this switch closes a circuit which stops the motor. Page 22... -
Page 25: Interference Switch
Interference Switch Interference Switch The Interference Switch is a (S.P.S.T.) normally closed switch. If an obstruction interferes with the downward motion of the snorkel, the switch opens a circuit that stops the motor. Page 23... -
Page 26: Trouble Shooting
Trouble Shooting Troubleshooting Testing components: The testing of the following components can be done at the relay board pin connectors. To test up limit switch: 1) Turn off electrical power to the unit. 2) Set the ohmmeter to the rx1 scale. 3) Touch the test leads to the common and the ul terminals on the J4 Pin connector of the relay board. - Page 27 Trouble Shooting To test down limit switch: 6) Turn off electrical power to the unit. 7) Set the ohmmeter to the RX1 scale. 8) Touch the test leads to the common and the DL ter- minals on the J4 Pin connector of the relay board. 9) The meter should indicate an open circuit.
- Page 28 Trouble Shooting To test down interference switch: 11) Turn off electrical power to the unit. 12) Set the ohmmeter to the rx1 scale. 13) Disconnect the black/blue wires from the interference switch to the control pcb. 14) Touch the test leads across the black/blue wires. 15) The meter should indicate an open circuit.
- Page 29 Trouble Shooting To test the motor step down transformer: 17) Turn off electrical power to the unit. 18) Set the ohmmeter to the RX1 scale. 19) Touch the test leads across the neutral and line terminals on the J6 pin connector of the relay board. 20) The meter should indicate approximately 18 ohms.
