ALARM FUNCTION
(RES-242 only)
ALARM SIGNAL
To increase the reliability of operation and to assure
adequate seals, the RES-242 controller contains a
comprehensive monitoring system that will send an
alarm signal (LED "ALARM" will turn red) and activate the
alarm relay when:
a) the heatseal element breaks, or any discontinuity in
the secondary circuit occurs.
b) ONE of the heatseal elements breaks when two
bands are mounted parallel.
c) A short circuit occurs at the heatseal element
d) Any discontinuity occurs in the monitoring wiring of
the heatseal element or the current transformer.
e) Any overheating of the heatseal element by 20%
above the controller´s operating temperature range
f) "Z" point is incorrectly set.
(see "START Function" and "Start Block")
To assure a trouble free "ZERO" calibration, functions e)
and f) will only activate after the start signal is given.
Other reasons for an ALARM signal are:
RESET
The controller can be reset - after the cause of the alarm
has been corrected - by pushing the "RESET" button or
by turning off the main power by at least 1 second.
Functions of the RES-241/242 (Continuation)
CYCLING TIMING
Heating and cooling cycle time follow each other.
Depending upon the program selected by use of the DIP
switch, the
either starts with the "START"
signal or when the heating element reaches the pre-set
temperature.
(see Section 4 "Timing Functions Programming").
The
always starts at the end of the
heating cycle. The maximum time duration for heating or
cooling is 9.9 seconds. Depending upon the program
selected, the duration of the cooling cycle may be set to
heating time
cooling cycle time
be a funtion of time or temperature. The cooling cycle may
be set to end when a pre-set temperature is reached, that
means that the relay K1 will drop out when the temperatu-
re drops below the pre-select level. The selection is done
by means of the 2 position digital selector switch in °C x 10
in increments of 10 degrees.
Selection 08 = 80 °C
Selection 12 = 120 °C

In the case of an alarm, the LED "ALARM" will turn red, the
controller output will be disabled, and the ALARM relay
will close between terminals 5 and 6.
