The "pick up" of a relay is a setting at which the relay will begin to operate. Such as an overcurrent relay - if the pickup is set to 5A, when 5A is flowing through the relay, the relay will operate.
A definite time over-current relay operates like an instantaneous over-current relay coupled with a timer. Once current reaches the pick-up value, it initiates the timing circuit. As long as current stays above this pick-up value, the timer will continue to time. Once the definite time setting is reached, the relay gives trip signal to the circuit breaker.
The way you check to see if an under voltage relay is wired properly is to disconnect the electrical supply. If the device that is connected to the load side of the relay does not start up or energize when the electrical supply is reconnected, then the relay is connected correctly.
I think aux relay is part of relay
Earth fault relay and an over current relay Methods to energies an earth fault relay with simulation diagram?
generator lockout relay is a relay that the output of other relays energize this relay and its out put use for tripping of generator. this relay must be reset manually
The starter relay is located on the battery side of the engine compartment on a 2002 F150 pick up truck. It is on the firewall close to the battery.
inside starter.
In the under hood relay/fuse center.
the blinker relay is behind the glove box
This is basically a differential relay that contains an additional restraining coil with the operating coil connected at its midpoint used to prevent the unnecessary pick up of the relay.
it's in the glove box!
Are you sure you pulled the right relay?
fuel pump relay is in fuse box under hood circuit opening relay is behind kick panel on passenger side
on the fire wall pass side
One of them should be the fuel pump relay.
A definite time over-current relay operates like an instantaneous over-current relay coupled with a timer. Once current reaches the pick-up value, it initiates the timing circuit. As long as current stays above this pick-up value, the timer will continue to time. Once the definite time setting is reached, the relay gives trip signal to the circuit breaker.
It is located in the engine compartment on the passenger side in the fuse panel it is called the EFI MAIN RELAY. Turn ignition switch on and listen for a clicking noise from relay.
