Applications
•
MENU KEY
Closing contact mimics the
MENU
key. In
OPERATION
Mode, pro-
vides entry to
TUNING
menu. In
SET UP
or
TUNING
Mode, advances
through the menus.
•
COMM. ONLY
Makes input status readable through communications (but has no
effect on the controller itself).
•
PV2.SWITCH
(only applicable for
PV SOURCE
= 1/2:SWITCH). Closing contact
causes the 535 to use PV2 as the PV input (instead of PV1).
Basic Operating Procedures
1. If more than one digital input closes and their actions conflict, the last digital
input that closed has priority.
For example, if one digital input closes and selects 2nd setpoint, and
then another digital input closes and selects a remote setpoint, the re-
mote setpoint takes precedence.
2. Any digital input can be overridden by: another digital input, a keyboard op-
eration, or an automatic function. If a closed digital input is overridden, then
it must be opened in order to be rearmed.
For example, if one digital input closes and selects the 2nd setpoint, and
then a different setpoint is selected through the keyboard, the keyboard
selection takes precedence.
J. REMOTE SETPOINT
Remote setpoint limits are the same as setpoint limits.
Hardware Configuration
•
The optional feature is available only if ordered originally from the factory,
Product #535-xxxxxBxx00 or #535-xxxxxExx00). Refer to the order code in
Chapter 1.
•
Before configuring the software, make sure the corresponding jumper is set
properly. Refer to Chapter 4 to check or change jumper positions.
Software Configuration
1. Go to the
CONFIG.
menu.
2. Set
REM. SET PT.
to ENABLED.
3. Go to the
REM. SETPT.
menu.
4.
TYPE V/MA
defines the input signal range (e.g. 1-5/4-20 mA).
5.
RSP:LO. RNG.
and
RSP: HI RNG.
define the range of the remote setpoint
in engineering units. The correct range will be dependent on the remote
setpoint signal source.
6.
RSP:LOW
and
RSP:HIGH
set limits on the remote setpoint value in
engineering units.
7.
TRACKING
determines whether or not the controller will revert to a local
setpoint if the remote setpoint signal is lost. This prevents a process upset
due to a sudden change in setpoint.
8.
BIAS LOW
and
BIAS HIGH
set limits on an operator entered bias value.
NOTE
: There is a one-second delay
before a closed digital input takes
action.
