successfully, 

an 

error 

message 

appears

(

section 9.18 "Error messages" on page 37).

You  should  always  wait  for  the  heatsealing
band  and  the  bar  to  cool  down  (to  ambient

temperature)  before  activating  the  "AUTOCAL"
function.

Reasons for disabled AUTOCAL function:

1. The "AUTOCAL" function cannot be activated if the

heatsealing band cools down at a rate of more than
0.1K/s. This is additionally indicated in the Settings
menu (step 107) by the message "Heatsealing band
still hot! Please wait...".
This message is also displayed if the unit cannot be
calibrated when the external "AUTOCAL" signal is
active (cooling rate too fast).

2. If the "START" signal on the temperature controller

is  activated,  the  "AUTOCAL"  function  is  not
executed.  This  is  additionally  indicated  in  the
Settings menu (step 107) by the message "Autocal
disabled! (START signal active)".

3. If  the  "ALARM-IN/RESET"  signal  (24VDC)  is

activated, the "AUTOCAL" function is not executed.

4. The AUTOCAL function cannot be activated if error

codes 101…103, 109 (up to software revision 202),
201…203, 801, or 9xx occur when the RESM-5 is
started  up  (

section 9.18  "Error  messages"  on

page 37).  It  cannot  be  activated  with  error  codes
201…203, 801, or 9xx if the RESM-5 has operated
correctly at least once since startup.

9.9

"ALARM-IN/RESET" signal

The  RESISTRON  monitoring  device  RESM-5  can  be
reset  by  means  of  an  external  "ALARM-IN/RESET"
signal (terminals 7+14). As a result of this:

• A  message  appears  on  the  display  (if  no  alarm  is

indicated by the RESM-5)

• The  standby  monitoring  function  for  the  main

controller to be monitored is activated (provided this
function  has  been  activated  with  step 229  in  the
Configuration menu)

• An error message is reset if one is present

(Note:  The  error  message  is  not  reset  until  the
"ALARM-IN/RESET" signal is deactivated)

The  actual  value  output  changes  to  0…3°C  (i.e.
approximately  0VDC)  while  the  "ALARM-IN/RESET"
signal is being activated.
The 

message 

"ALARM IN / RESET active" 

is

additionally  displayed  on  the  RESM-5  when  the
"ALARM-IN/RESET" signal is active.
The  "AUTOCAL"  function  is  not  canceled  if  the
"ALARM-IN/RESET"  signal  is  activated  while  it  is  still
executing.

Note the configuration of the alarm output in
the Configuration menu (step 215) if you use

the ALARM-IN/RESET signal (

section 8.2.7 "Con-

figuration of the alarm output" on page 19

)

.

The 

RESM-5 

performs 

an 

internal

initialization  lasting  approximately  500ms

after the "ALARM-IN/RESET" signal is deactivated.
The unit is not ready to operate again until it has
finished.

9.10

AUTOCAL function disabled

The  "AUTOCAL"  function  can  be  configured  with
step 213 in the Configuration menu when  step 107 is
displayed.
This  prevents  the  heatsealing  bands  from  being
inadvertently calibrated if the "ENTER" key is pressed.
Disabling this function has no effect on the calibration
