Programme/Software Update Using Programme Diskette At The Unit - Endress+Hauser memo-graph Version II Betriebsanleitung

Relay function in alarm condition, when active. Closing contact: Connections 41-44
are closed in alarm condition, when inactive the connection is 41-42.
Opening contact: Connections 41-42 are closed in alarm condition. when inactive the
connection is 41-44.
Hint: In this mode the relay coil is under current. This means the relay can be used as
a power failure transmission contact as the contacts 41-42 are closed in the case of
an "alarm condition" or power failure ("maximum safety").
Relay function in alarm condition, when active.
"Closing contact": Respective connections (shown in brackets) are closed in alarm
condition, when inactive the connections are open.
"Opening contact": Respective connections (shown in brackets) are closed in alarm
condition, when inactive the connections are open.
Hint: In this mode the relay coil is under current in normal operation. This means the
relay can be used as a power failure transmission contact as the contacts 41-42 are
closed in the case of an "alarm condition" or power failure ("maximum safety").
Open collector output function in alarm condition, when active.
Hint: The open collector is an NPN transistor, terminal 98 = collector, terminal 99 =
emitter, reference potential.
"Yes": Instead of the instantaneous value the display indicated the frequency
measured via the EPLD. - Only for service purposes!
• Calibration: Factory settings for the clock IC and rear panel temperature.
Do not change, could cause faulty function of the unit. Calibration only
possible using the PC calibration routine. Must only be done by skilled and
trained personnel.
Quartz clock IC calibration.
Rear panel temperature, correction value for analogue board 1 (channels 1...8) and/or
2 (channels 9...16).
1. Save the unit set up at the PC ("Functions /unit/create parameter diskette") on a
new diskette.
2. Switch the unit off.
3. Place the new original programme diskette into the unit.
4. Simultaneously hold the second and third push button from the left when switching
the unit back on. Hold these until the green LED flashes.
5. Release the push buttons. The new programme will now be loaded (lasts for
approx. 5 minutes). The screen remains dark during the load phase, green LED
flashes. Acknowledge the RESET message with OK.
6. When required load the previously saved set up parameters back into the unit.
("Diskette functions/ load set-up from diskette").
Attention: When updating a programme all settings found in the unit memory and on
diskette are deleted.
