Description and Configuration Options
Select Loss of Signal
Position
(B-0)
Position Index #0
(Minimum)
Desired valve position when a loss of signal (L.O.S.) event occurs. A loss of signal condition exists if the position
command signal drops below 0.05 mA. Configuration setting #0, 1, 2, and 3 correspond to the positions defined at
index #0, 3, 6, and 9, respectively. Setting #4 corresponds to no position change (i.e. valves remain in last position
before loss of signal).
Select Control
Deadband
(B-3)
0.06% Deadband
(#2)
Control deadband placed around the position command input signal to eliminate unwanted actuator movement
caused by electrical noise on the 4-20 mA position command. Configuration setting #0, 1, 2, 3, 4, and 5 corre-
spond to a deadband of 0, 0.03, 0.06, 0.13, 0.16, and 0.19%, respectively.
Select Startup
Configuration
(B-4)
Default Startup
(#0)
The Startup Configuration setting defines what effect the startup command inputs have on SMARTLINK

MRV
operation. The 3 startup commands include the Purge Position Command (PPC), Lightoff Position Command
(LPC), and Standby Position Command (SPC). The SPC command is active when both the PPC and LPC com-
mand inputs are not energized.
Default Startup (#0): PPC = maximum position for all valves, index #9; LPC = minimum position for all valves,
index #0; SPC = minimum position, index #0. For this configuration setting, adjustment of the minimum position
(Index #0) and maximum position (Index #9) will automatically change the purge (Index #10), lightoff (Index
#10.5), and standby (Index #9.5) positions.
Custom Startup (#1): For each valve, the user can define a position for each of the 3 startup commands (PPC,
LPC, SPC). This configuration setting enables Command B-1 (Set Purge Position), Command B-2 (Set Standby
Position), and Command B-5 (Set Light-Off Position).
Set Auto Ramp Adjust
(B-6)
Auto Ramp ON
(#1)
The automatic ramp function is used during the Valve Position Setup Mode to create a linear position ramp
between the position being adjusted and the two adjacent position indexes. This provides a position "smoothing"
of the valve profile and simplifies valve characterization. Setting #0 is Auto Ramp OFF and setting #1 is ON.
Select Movement
Configuration
(B-7)
Medium
(#1)
The speed of valve movement from low to high fire can be selected using the Select Movement Configuration
Command. Configuration setting #0 is the slow speed (~60 seconds), setting #1 the medium speed (~40 sec-
onds), and setting #2 is the fast speed (~20 seconds).
Enter New Lock
Passcode
(C-4)
Passcode:
0,0,0,0
(N/A)
4-digit electronic passcode to prevent tampering. To change the existing passcode, the lock function must be
enabled and the unit must be "unlocked". See Select Lock Enable/Disable configuration below.
Select Lock Enable /
Disable
(C-5)
Lock Disable
(#0)
Enable / Disable selection of the electronic "lock" function. If enabled, the stored passcode must be entered to
modify any configuration or valve profile data. Setting #0 and #1 correspond to Lock Disable and Lock Enable,
respectively.
