Booster connection
The RES-445 controller has a connection for an
external switching amplifier (booster) as standard. This
connection (at terminals 1+2) is necessary for high
primary currents (continuous current > 5A, pulsed
current > 25A). The switching amplifier should be
connected as described in Kap. 8.7 „Wiring diagram
with booster connection“ auf Seite 17. No settings are
required in the menu.

Time control (timer function)
10.19.1 Activation and indication
The settings described here are only allowed
to be entered by technically trained persons.
An incorrectly parameterized timer function may
cause disruptions to operation and damage to the
machine.
The timer function is activated with step 26 in the
Configuration menu:
There are two possible settings in this menu:
1.
"OFF"
(•)
Time control (timer function) deactivated
2.
"ON"
Time control (timer function) activated.
The internal timeout is started by activating the
"START" signal. The timeout either ends with the
parameterized cooling phase or is interrupted by
activating the "RESET" signal.
3.
"ON with START monitoring"
(software revision 021 or higher)
Time control (timer function) activated and "START"
signal monitored.
Once again, the internal timeout is started by
activating the "START" signal. In this setting,
however, the "START" signal must remain activated
until the end of the parameterized cooling phase. If
the "START" signal is deactivated before the end of
the cooling phase - or if the "RESET" signal is
activated - the timeout is interrupted.
If time control is on, activating the "START" signal starts
the internally parameterized timeout. This timeout
comprises:
• Starting delay (delay at the beginning of the heating
phase)
• Heating phase (heating and control process)
• Cooling phase
• Relay K1 function
If time control (timer function) is activated, it
is only possible to start a heating process
with the "HAND" key on the controller. The timeout
of the internal time control cannot be started with
this key.
The timeout of the internal time control (timer
function) can be interrupted by activating the
external "RESET" signal (software revision 009 or
higher) or by switching off the controller. As of
software revision 021, it can also be interrupted by
deactivating the "START" signal if time control "ON
with START monitoring" is configured.
If the display is in the home position, the individual
timeouts can be monitored there.
The remaining heatsealing time is indicated on the
display in the form of a countdown at the end of the
