RES-440
Version 1
As of software revision 100:
If time control (timer function) is deactivated, the same configuration options are available for "Output 1" as for
relay K1 (
section 9.3.8 "Relay K1 (without time control)" on page 27). The options for "Output 1" are specified
with step 222 in the Configuration menu as followed:
1.
"Off"
"Output 1" has no function
2.
"Active if Tact = Tset"
Output 1 is conductive if the actual value is inside the specified temperature tolerance band (steps 207, 208).
If the actual temperature is outside the tolerance band, "Output 1" is not conductive.
This function is the same as for the "Temperature OK" signal up to software revision 027.
3.
"Active if Tact = Tset", with latch function
(factory setting)
"Output 1" is conductive if the actual value is inside the specified temperature tolerance band (steps 207, 208).
If the actual temperature leaves the tolerance band once while the "START" signal is active, "Output 1 is no
longer conductive. "Output 1" does not become conductive again until the next "START" signal is activated and
can thus also be interrogated by the higher-level PLC after a heatsealing process.
Other settings are available in this menu when time control (timer function) is active. They are described in
section 10.23.8 "“Output 1“/ “Temperature OK“ signal (with time control)" on page 72.
9.3.10 Temperature diagnosis (as of software revision 100)
The temperature diagnosis function can be activated by means of step 217 in the Configuration menu. The
RES-440 then checks whether the ACTUAL temperature is inside a specifiable tolerance band ("OK" window) on
either side of the SET temperature. The lower (
) and upper (
) limits of the tolerance band can be
changed independently of one another by means of steps 207 [24] + 208 [25] (factory setting: -10K or +10K).
If the ACTUAL temperature is inside the specified tolerance band when the "START" signal is activated, the tem-
perature diagnosis is also activated. If the ACTUAL temperature leaves the tolerance band, the corresponding
error code (307, 308) is indicated and the fault output is switched (
section 10.26 "Fault areas and causes" on
page 81). If a heatsealing cycle is in progress, it is immediately interrupted.
If the temperature diagnosis is not activated by the time the "START" signal is deactivated (i.e. if the ACTUAL tem-
perature does not exceed the upper or lower tolerance band limit), the corresponding error code (309, 310) is indi-
cated and the fault relay is switched.
If the temperature diagnosis function is activated, an additional delay time of 0 to 9.9s can be parameterized for
the temperature timeout with step 218 in the Configuration menu. The first time the lower tolerance band limit is
exceeded, the temperature diagnosis is not activated until the parameterized delay time has elapsed. The tem-
