Remote Signalling Alarm; Before Start Up; Start Up - omi ED 18 Instruction And Maintenance Manual

3.1.4 REMOTE SIGNALING ALARM
Alarm Output relays electric
features:
Max. 250VAC / 3A – AC 15 (Amp. Inductive)
The activation of the above function is on User's discretion. The User will purchase all necessary
installation material by himself. Any operation which needs access to the dryer must be carried out by
qualified personnel.

3.2 BEFORE START UP

Before starting the machine, make sure that all operating parameters correspond to the nominal data.
The dryer is supplied already tested and preset for normal operation, and it doesn't require any calibration.
Nevertheless, it's necessary to check the operating performances during the first working hours.

3.3 START UP

The operations specified below must be performed after the first start up and at each start up after a prolonged
inactive period of time due to maintenance operations, or any other reason.
1. Make sure that all instructions contained in chapters INSTALLATION SITE and INSTALLATION have been
respected.
2. Check if by-pass is locked properly (if existent).
3. Activate current supply and press the ON/OFF switch on the control panel for at least 1 second.
Only on Mod. 780 ÷ 1000 Nm3/h
- Turn main power switch on position 1.
- Wait for 8 hours before starting the dryer
(the warranty is not valid if this procedure is not respected).
4. Wait 5 to 10 minutes until machine has achieved its standard operating parameters.
5. Slowly open the air outlet valve and successively open the air inlet valve.
6. If existent, close the by-pass.
7. Check if the condensate drainer is working properly.
8. Check if all connecting pipes are properly tightened and fixed.
Before disconnecting the dryer from electrical power supply, use ON/OFF key to stop the dryer.
Otherwise wait 10 minutes before switching the dryer on again, in order to allow freon pression
re-balance.
Cod. 710.0138.01.00 Rev1C – 09.2009
The dryer control board is equipped with a digital output for the remote signalling alarm. This
digital output is controlled by a relays configured as normally open: when an alarm is
detected, this relays closes a circuit.
Proceed as follows to activate a remote alarm output:
1. The User must provide a signaller in compliance with output relays electrical features
(solenoid coil, light bulb, acoustic signaller, ...).
2. Disconnect the dryer from electrical power supply, remove cover and left side panel.
3. Connect the signaller to the terminal blocks (See PIC.3).
