EY Beckhof HEPI Controller - Level Sensor Monitoring
ECR E2200043
A RIB2401D relay was installed at EY for monitoring the HEPI reservoir level on 7/1/2026. The same scheme is used in the corner station. The RIB2401D relay is enabled by the reservoir level sensor. The outputs of the RIB2401D will be used to enable the motor control panel and status readback signal of the level sensor. The EL1094 terminal was replaced with EL1004.
While installing the new RIB2401D relay we glitched the 24V. This caused the Vacuum Beckhoff computer to reboot. See alog 90866.
