In order to permit a proper calibration functions e) and f)
are activated only when there is a start signal.

Other reasons for an alarm signal could be:

Incorrect voltage range chosen (DIP switches 15)

Incorrect frequency rating selected (Jumper 13 )

Incorrect voltage supply (e.g. 230V vs 115V)

Internal malfunction

The malfunction is signaled by the LED "ALARM".
The controller output is disabled and will remain in this
state.
The alarm relay is activated
(contact between 5and 6 is closed).

To increase operating safety and to assure adequate
seals, the RES-220 controller contains a comprehensive
monitoring system that will send an alarm signal (LED
"ALARM"(4)will turn red) and activate the alarm relay
when:

a) Heatseal element breaks, or any discontinuity in the

secondary circuit occurs.

b) When one of the heatseal element breaks when two

are connected in parallel.

c) A short circuit occurs at the heatseal element.

d) Any discontinuity occurs in the monitoring wiring for

voltage U or I .

e) Heatseal element overheats by 20 % over the

maximum temperature (hotter than 360°C).

f)

Calibration was performed incorrectly (suppression of
the "Z" point). (See "START" and "START Block")

Reset

The controller can be reset - after the cause of the malfunction has been corrected - by pushing the "RESET" button,

or by turning off the main power by at least 1 second.
