Variable-Frequency Drives Ð The input signal for the inverter must be 4 to 20 mA. Use a 2-conductor 20 AWG (American Wire Gage) cable (single twisted pair, unshielded) to connect the input of the inverter to the output of the PIC control terminals. See Fig. 8.

Wire the inverter so that if it is placed in the manual or bypass mode the low temperature thermostat and the high- pressure switch (if supplied) are still in the motor control circuit to protect the unit.

Adjust the minimum inverter speed to provide at least 10% air¯ow when inlet guide vanes are at 0% (4 mA) and maxi- mum design air¯ow when inlet guide vanes are at 100% (20 mA). Use the local interface device to verify that the

supply fan status ( ) shows the fan is ON and that the

supply fan is operating at the lowest air¯ow adjustment. In- crease inverter minimum speed as required. For additional information, see the Quick Test section on page 103.

Water Valve Assemblies Ð Water valve assemblies (Fig. 13) are shipped inside the fan section for ®eld instal- lation. All valve assemblies have electrically powered ac- tuators. Each actuator has an external junction box for ®eld wiring. The junction box contains 24 vac power wires (WHITE/ BLUE, BLACK) and 4 to 20 mA signal wires (1RED, −GREEN). The actuators operate the valve through a linear stroke; if power is lost, a return spring reverses the stroke and returns the valve stem to the normal position.

To prevent electric shock and equipment damage, dis- connect the power to the control box before installing valve assemblies. Turn power switch located on control box door to OFF.

On installations where valve mounting space is limited, use unions to couple valve assemblies to water lines. If unions do not provide sufficient clearance, refer to the Valve Troubleshooting section, page 109.

On chilled water applications or hot water applications with 11¤2 to 3-in. valves, the valve actuators can be mounted in any position above the centerline of the valve body. For steam applications or hot water applications with 1¤2 to 11¤4-in. valves that have actuators and high-temperature linkage exten- sions, mount the actuator above the centerline of the valve body and 45 degrees from vertical. This position helps to prevent actuator exposure to direct heat convection.

DO NOT install valve assembly where excessive mois- ture, corrosive fumes, and/or vibration are present.

INSTALL all 2-way valve assemblies so that they close against system ¯ow. An arrow on the valve body indi- cates the proper ¯ow direction.

ALWAYS install 3-way mixing valve with 2 inlet ¯ows and one outlet. Normal ¯ow will be from port B to port AB with stem up. See Fig. 14.
