Figure 1-3 (above) shows a detailed view of the switches and indicators
located on the front of the VDM300. The following is a description of each
switch and indicator.
ZERO: This is a momentary detent switch that activates a zeroing function to
remove any zero offset that may have accumulated over time during normal
VDM300 operation. Refer to the section called VDM300 Zeroing later in this
manual for information on when and how to use this function properly.
DEVICE READY: (Green LED)This indicates when the VDM300 is Ready-
to-Use (RTU). lt also serves as an indicator when a drain cycle is complete
(blinkíng).
WARM UP: (Amber LED)This indicates when the VDM300 is warming up
(solid) or at the desired temperature (blinking).
DEVICE FAULT: (Red LED) This indicates an alarm/fault condition.
ECAT ERR: (Red LED) Indicates EtherCAT error status. See the Supple-
mental Manual for Brooks Instrument EtherCAT for VDM300 Series ( X-DPT-
VDM300-EtherCAT) for details on the various states.
ECAT ID: These three 16-position rotary switches (X100, X10 and X1) are
used to set the serial address for the VDM300 device in EtherCAT communi-
cation networks. The three switches create a 3-digit address as in the follow-
ing example: if the X100 switch is set to "A", the X10 switch to "5" and the X1
to "B", the serial address would be "A5B".
