Install the BYP200 according to the guidelines available in the Verasys ZEC310 Zone Damper and BYP200 Bypass Damper Controllers Installation Guide 24-10143-1248 . To check the bypass damper, complete the following steps:
- Log on to the SBH300.
- Select the COBP damper from the Device list. The Bypass Damper menu appears. From the BYP200 home page you can view how the damper controls the zone.
- Start the supply fan. Ensure some zones are blocked to relieve pressure.
- Check the differential pressure sensor to ensure correct value.
- Navigate to the Setup tab and complete the
following steps:
- Set the damper direction to Close on the damper.Note: This setting only affects the internal actuator built into to the controller. The controller has the option to add a second actuator wired to a 0 V to 10 V output. When you use the M9106-GGA-2 actuator, a jumper setting determines the direction to close on the second damper. Other actuators need to have the option to switch the action of the actuator with a jumper or a switch.
- Verify the second actuator, if installed.
- Set the Unit Enable to Enable.
- Set the damper max position to limit how much the damper is allowed to open.
- Set a Differential Pressure Setpoint that the damper can maintain.
- Navigate to the Bypass home page to monitor operation and adjust the Duct Pressure Setpoint to the required value.
- Set the damper direction to Close on the damper.
