check that they are functioning properly. Do this for both outputs if equipped by
changing the Element Interlock from one vessel to the other.
Operation
The BruControl application and the UniFlex are two components in a functioning BruControl
integration and operate like all BruControl systems. Therefore, it is critical that the user review
the
in its entirety before operating the UniFlex. The operation
instructions to follow assume awareness and understanding of the User Manual content and
will not be repeated here for consistency.
Power Flow & Control
For the Vessel Power Outputs, the 240VAC power routes through the UniFlex as follows:
This power flow requires both the SSR (Solid State Relay) and Interlock Relay to be ON in order
for the output to be powered. Note: For single vessel configurations, only one Interlock Relay
and Power Output Receptacle are included.
For dual vessel configurations, BOTH Interlock Relays MUST NEVER be ON at the same
time. In the pre-defined configurations provided, the “Dual Throw” function of the Interlock
Relays and a safety script are implemented to prevent this from occurring. If however a manual
configuration is created or used by a user, failure to ensure that only one Interlock Relay is ON
will create a current overload, possibly causing damage to the UniFlex or supporting circuitry.
The SSR is controlled both by the “PID Control” PID Device Element or by the “Manual Control”
Device Element. PID Devices uses a PID (Proportional Integral Derivative) algorithm to achieve
and maintain a set temperature by comparing it to the current actual temperature. Its output
varies from cycle to cycle, creating a net power output from 0 to 100%. It uses an input
temperature to reference the actual temperature, which is selectable from the various
temperature probes established. The power output will be either duty cycle or PWM,
depending on the respective setting in the PID Device Element properties, which should match
the SSR type (duty cycle for standard and PWM/analog for proportional SSR’s.
“Manual Control” will be a Duty Cycle Device Element for standard (binary) SSR configurations
or a PWM Output Device Element for proportional SSR configurations. This device also
generates a net power output from 0 to 100%, but this output is set by the user and remains
fixed.
