X. OPERATION
For UBEC2, UBEC3 and UICS2, pressure and flow information from sensors or from the datalink
interface is processed and displayed.
On power-up the valve control will be in the normal operating mode. The OPEN, CLOSE and PRESET buttons will
control valve position. The PRESET button will set the valve to a programmed position.
The red CLOSED LED will be on when the valve is in the fully closed position. The VALVE POSITION indicator will
show the valve position with ten green LEDs (1 LED on, valve 10% open; 10 LEDs on, valve fully open).
For the UICS2, the CAF ON LED is lit when the compressed air foam control is activated and the CAF SELECT
button sets the valve at a pre programmed position.
1. Datalink Interface
The Elkhart Brass datalink interface is standard on all valve controllers and provides a way of connecting
multiple display modules on a shared CAN data bus.
Each valve control is programmed as a primary or remote display. When a control is programmed as a
remote, the ID Number must be the same as the primary it is matched to.
Refer to Programming section on Pages 53-62.
The primary control will send data to the remote(s) via the datalink.
– Both primary and remote will operate the valve.
– The primary will override a remote if buttons are pushed at the same time.
– All calibration data will be updated from the primary to remote at power up.
– Either primary or remote can be used to reprogram the preset position.
2. Primary Control and Display Module (Secondary)
Primary displays are programmed with the module function Pri. A primary display receives input from the
valve, pressure sensor and flow sensor. When it is programmed with ID 0 it will not output information on
to the datalink. When it is programmed with ID 1 to ID 99 (ID 10 is maximum for UBEC1), it will provide
information (via the datalink) to remote displays.
3. Remote Control and Display Module
Remote displays are programmed with the module function SLA (slaved to a primary). A remote display
must be programmed with the same ID number as a primary display. It will receive information for the
display of valve position, pressure and flow rate from the primary display over the datalink. All program
code features are programmed independently of the primary display. No calibration is necessary on a
remote display.
4. External Switches
Switches
Control of the E3F, E4F, E5F, and E6F electric actuator can be achieved though the use of external switches
by supplying a ground signal to the designated pins on the control module. The pin designation can be
found in the Wiring section on Page 68.
Note: If switches are used in conjunction with any other control method, the switches will always
function as the primary control for the valve.
Valve Position Indication Light (E3F, E4F, E5F, & E6F)
Two pins on the E3F, E4F, E5F, and E6F electric actuator control module have been designated as optional
valve position indication lights. The pin designation can be found in the Wiring section on Page 70.
1. The CLOSE light output pin supplies 12 VDC. This pin can be utilized by connecting a light between this
pin and ground. The CLOSE light will be turned on when the valve is fully closed.
2. The OPEN light output pin supplies ground. This pin can be utilized by connecting a light between this
pin and a 12 VDC supply. The OPEN light will be turned on when the valve is fully open. The OPEN light
will flash when the valve is in between the fully open and fully closed position.
