Configuration 6, Serial Communications

*

“bAUd” - Select baud rate

“PArb” - Select parity bit

“Addr” - Enter unit address number

“Abrv” - Select abbreviated or full mnemonic

transmissions

“PrAt” - Enter automatic print rate

“PoPt” - Select parameters to be included in print-out

Configuration 7, Second Input

“OPEr” - Select remote setpoint or internal

cascade mode

“root” - Select second input square root linearization

“dPt2” - Select second input decimal point

“dSP1” - Enter scaling parameters of second input

“INP1” - Enter scaling parameters of second input

“dSP2” - Enter scaling parameters of second input

“INP2” - Enter scaling parameters of second input

“SPtr” - Enter local/remote select options

“OPd2” - Enter Secondary output control dampening

Configuration 8, Motorized Valve Positioner

*

Position mode: “VPS1” - Enter or measure valve closed position

“VPS2” - Enter or measure valve open position

“VUdt” - Enter valve update time

“VPdb” - Enter valve control deadband

HIDDEN FUNCTION MODE *

The hidden function mode is accessible from the normal operating mode. The

four functions in this mode may be locked-out individually in configuration 3

parameter lock-out section.

“SPSL” - Select Local/Remote Setpoint

“trnF” - Transfer between automatic (PID) control

and manual control

“tUNE” - Invoke/cancel PID Auto-tune

“ALrS” - Reset latched alarms

PROTECTED PARAMETERS MODE *

The protected parameters mode is enabled when program disable is active.

This mode prevents access to the configuration modes without the proper access

code number. Only the parameters that are selected in the configuration 3

parameter lock-out section can be accessed.

“ProP” - Enter Proportional band

“Intt”

- Enter integral time

“dErt” - Enter derivative time

“rtio”

- Enter remote setpoint ratio value

“bIAS” - Enter remote setpoint bias value

“SP-2” - Enter internal cascade, secondary setpoint

“Pb-2” - Enter internal cascade, secondary

proportional band

“It-2”

- Enter internal cascade, secondary

integral time

“dt-2” - Enter internal cascade, secondary

derivative time

“AL-1” - Enter value for alarm #1

“AL-2” - Enter value for alarm #2

“CodE” - Enter access value to unprotected

parameters & configuration parameters

*

These parameters may not appear due to option configuration or other

programming.

ACCESSORY - EXTERNAL RLY50000 SSR

POWER UNIT SHOWN

(External DIN Rail mount SSR power units available)

The external SSR Power Unit is used with the Logic/SSR Drive Module

(OMD00003) to switch loads up to 240 VAC @ 45 amps, 25°C ambient.

The unit is operated by applying a low level DC control signal to the

isolated input. The unit features zero cross detection circuits which reduces

radiated RFI when switching load currents. With no contacts to wear out,

the SSR Power Unit provides virtually limitless operational life. The unit is

supplied with an integral heat sink for immediate installation.
