Heatup timeout
(as of October 2005)
An additional heatup timeout can be activated in the
ROPEX visualization software (
ª
section 6.10 "Dia-
gnostic interface/visualization software (as of October
2005)" on page 25).
This timeout starts when the START signal is activated.
The RES-403 then monitors the time required for the
ACTUAL temperature to reach 95% of the SET tempe-
rature. If this time is longer than the parameterized
time, the corresponding error code (304) is indicated
and the alarm relay is switched (
ª
section 6.12 "Error
messages" on page 26).
6.10
Diagnostic interface/visualization
software (as of October 2005)
An interface with a 6-pole Modular Jack (RJ-12) is pro-
vided for system diagnostics and process visualization.
This interface allows a data connection to be set up to
the ROPEX visualization software using the ROPEX
communication interface CI-USB-1.
Only a ROPEX comunication interface is
allowed to be connected to the diagnostic
interface. Connecting another device (e.g. a
telephone cable) could result in malfunctions or
damage to the controller.
The ROPEX visualization software is described in a
separate document.
6.11
System monitoring/alarm output
To increase operating safety and to avoid faulty heatse-
aling, this controller incorporates special hardware and
software features that facilitate selective fault detection
and diagnosis. Both the external wiring and the internal
system are monitored.
These features assist the operator in identifying the
cause of abnormal operations.
A system fault is reported or differentiated by means of
the following indications.
A.)
Red "ALARM" LED on the controller
three states:
1.
Blinks fast (4Hz)
The AUTOCAL function should be executed (error
codes 104…106, 211, 302, 303; up to September
2005: error codes 8+9).
2.
Blinks slowly (1Hz)
The system configuration is incorrect and the zero
calibration (AUTOCAL function) was unsuccessful
(
ª
section 5.11 "Controller configuration" on
page 13). It corresponds to error codes 110…114
(up to September 2005: error codes 10…12).
3.
Lit continuously:
This indicates that a fault is preventing the controller
from being started (error codes 101…103, 107, 108,
201…203, 307, 308, 801, 9xx; up to September
2005: error codes 1…7).
As a rule, it refers to an external wiring fault.
B.)
Alarm relay (relay contact terminals 5+6):
This contact is set in the factory as follows:
•
OPEN
in operating states A.1) and A.2), but closed
if a "START" signal is activated in one of these
states.
•
CLOSED
in operating state A.3)
If the alarm relay is configured opposite to the factory
setting (
ª
section 5.11.3 "Configuration of the alarm
relay" on page 15), these states are reversed.
