Keep all wires
away from
the jumper
block areas.
1. Current Sensor: In-series current sensor for motor status.
2. Power Terminal Block: Wire the H540/548 in series with the motor using these
terminals.
3. Relay Coil Terminal Blocks: Wire the output signal from the control panel to
actuate the relay. 24 VAC/DC; 36mA nominal.
4. Status Terminal Blocks: Wire the status input back to the control panel.
5. N.C. Relay Jumper Block: Insert a jumper here to ensure normally closed relay
operation when the switch is in auto. Disconnect power to the device before
before touching the jumper.
6. H.O.A. Switch: Control the motor locally.
HAND – When the switch is in this position, the motor is always on.
OFF – When the switch is in this position, the motor is always off.
AUTO – When the switch is in this position, the control system commands the
motor.
7. Relay Status LED: For positive indication of energized coil.
8. Relay: Enables actuation of circuit by a control system.
9. N.O. Relay Jumper Block: Insert a jumper here to ensure normally open relay
operation when the switch is in auto. Disconnect power to the device before
before touching the jumper.
10. Status Open LED: Indicates that the current is below the trip point and the
status contact is open (used to calibrate the current switch in H548 models only).
11. Current Switch Set-Point Screw: Used to adjust the point in the current range
at which the current switch will change states (used to calibrate the current
switch in H548 models only).
12. Status Closed LED: Indicates that the current is above the trip point and the
status contact is closed (used to calibrate the current switch in H548 models only).
CAUTION!
Do not rely on status indicators to determine whether or not the relay contacts are
connected to a power source. Doing so may result in injury or death from electrical
shock.
If the connections to the unit are made through more than one metallic conduit, bond
the conduits to prevent the hazard of electric shock. A bonding plate is available (Veris
part AH10).
setting contact jumper
The H540/548 has a jumper for N.O. or N.C. relay function. The jumper affects the
relay contacts only when the HOA switch is in AUTO. The product is shipped with the
jumper in the N.O. position. To select N.C. function, move to the N.C. jumper block.
Always disconnect power to the device before before touching the jumper.
