Conn (Connection) MAIN MENU

The Conn menu contains SUB MENUS to configure the RS-485 serial parameters and

selected protocol. The SUB MENUS are:

• Prot - Protocol

• ADDR - Protocol Address

• bAUd - Serial Baud Rate

• PAr - Serial Parity

• StP - Serial Stop Bits

Prot (Protocol) SUB MENU

• MOD - Modbus

Communication (factory setting)

• BAC - BACnet Communication

• NONE - Communication disabled

ADDR (Protocol Address) SUB MENU

This value sets the RS-485 device address. See the table below for protocol specific

ranges. The factory setting is 127. SUB MENU not available if protocol is NONE.

bAUd (Serial Baud Rate) SUB MENU

• 96 - 9600 bps

• 192 - 19200 bps

• 384 - 38400 bps

• 576 - 57600 bps

• 768 - 76800 bps

• 1152 - 115200 bps

• AUTO - Auto-baud (factory setting)

If the selected protocol is Modbus

communication, the AUTO setting will also

determine the serial parity and serial stopbits. If selected communication protocol is

BACnet, serial parity and serial stop bits are fixed to NONE and 1 respectively. SUB

MENU not available if protocol is NONE.

PAr (Serial Parity) SUB MENU

• EVEN - Even Parity (factory setting)

• ODD - Odd Parity

• NONE - No Parity

SUB MENU not available if protocol is NONE or BAC or if serial baud rate is AUTO.

StP (Serial Stop Bits) SUB MENU

• 1 - One stop bit

• 2 - Two stop bits

SUB MENU not available if protocol is NONE or BAC or if serial baud rate is AUTO.

CAL (Calibration) Main Menu

The CAL menu contains SUB MENUS to perform field calibration, reset settings, and

display information. The SUB MENUS are:

• ZERO - Zero Calibration

• SPAN - Span Calibration

• rSt - Reset Factory Defaults

• Sn 1 - Display Serial Number part 1

• Sn 2 - Display Serial Number part 2

ZERO (Zero Calibration) SUB MENU

For accurate calibration, do not apply any pressure when performing this function.

Press and hold the ENTER button unit the process value is cleared. The display will

show a dash in each digit starting with the left most position. After 4 dashes have been

displayed, the process value will be displayed and the new zero will be applied. For

best results, perform the zeroing function in the same orientation you will mount the

DHC.

SPAN (Span Calibration) SUB MENU

For an accurate calibration, perform a Zero calibration first. The pressure to apply

will depend on the selected mode and the POH, VOH or FOH value. Apply a stable

pressure equal to the configured output high value. Press and hold the ENTER button

until the process value is cleared. The display will show a dash in each digit starting

with the left most position. After 4 dashes have been displayed, the process value will

be displayed and the new span will be applied. If the span cannot be applied, a FAiL

message will be displayed. This error could occur if the applied pressure is too low or

too high.

rSt (Reset Factory Defaults) SUB MENU

• NO - Do nothing

• YES - Reset all settings, clear user calibration

After selecting YES the instrument will reboot itself.

Sn 1, Sn 2 (Serial Number Display) SUB MENUS

The serial number of the instrument can be viewed on the display using these menus.

The first 4 characters are available with Sn 1 and the second 4 characters are available

with Sn 2.

SPAL (Set Point/Alarm) MENU

The SPAL menu contains the set point trigger and reset value as well as the alarm

limits. This menu is accessible from the home screen with the SPAL button. If both set

points and both alarm limits are disabled, then the SPAL menu will contain no SUB

MENUS and pressing the SPAL button will not do anything. The SUB MENUS are:

• SP1T - Set Point 1 Trigger

• SP1R - Set Point 1 Reset

• SP2T - Set Point 2 Trigger

• SP2R - Set Point 2 Reset

• ALLO - Alarm Low Limit

• ALHI - Alarm High Limit

SP1T, SP2T (Set Point Trigger) SUB MENUS

These SUB MENUS set the trigger value for each set point. When the process value

equals the set point trigger value, the set point is considered active. These SUB

MENUS are only present if their corresponding enable setting is set to ON.

SP1R, SP2R (Set Point Reset) SUB MENUS

These SUB MENUS set the reset value for each set point. When the process value

equals the set point reset value, the set point is considered inactive. These SUB

MENUS are only present if their corresponding enable setting is set to ON.

ALLO (Alarm Low Limit) SUB MENU

This SUB MENU sets the alarm low limit value. If the process value is less than the

alarm low limit value, the low alarm is considered active.

ALHI (Alarm High Limit) SUB MENU

This SUB MENU sets the alarm high limit value. If the process value is greater than the

alarm high limit value, the high alarm is considered active.

The range of the alarm limits depends on the selected mode. If both low and high

alarm limits are enabled, they cannot be closer than 2% of full-scale to each other. The

dead bands of the alarm limits are fixed at 1% of full-scale.
