RES-407
MOD 21
Inverts the alarm signal (terminal 18). If an alarm is
signaled, the alarm output is switched to open condition
(LOW). If the controller does not report an alarm, a
24VDC voltage level (HIGH) is output at terminal 18.
MOD 26
Additional terminal for connecting an external switching
amplifier (booster). This modification is necessary for
high primary currents (continuous current > 5A, pulsed
current > 25A).
MOD 37 (until May 2003)
Additional rotary coding switch for the heatsealing band
alloy and the temperature range. Various heatsealing
band alloys (e.g. Alloy-20, NOREX) and temperature
ranges (e.g. 300°C, 500°C) can be selected.
This modification is supplied as standard
with all controllers manufactured as of June
2003
(

section 9.2.2 "Configuration of the rotary
coding switch for the temperature range and alloy
(as of June 2003)" on page 20
)
.
MOD 40
Additional terminal for "Temperature reached" signal.
This output signal is activated when the ACTUAL
temperature of the heatsealing band exceeds 95% of
the SET heatsealing temperature. It can be used to
monitor the process, for example, or to control the
closure of the heatsealing bars.
MOD 40 cannot be used in combination with
MOD 26 (booster connection) manufactured
prior to March 2005.
