7.3.7 Unit status signal or maintenance pre-alert
(Installer menu)
The humidifi er controller is fi tted with a relay contact for remotely
signalling unit status (production) or a maintenance pre-alert. Terminals
M5.1 and M5.2 are used for these functions.
Index Description Parameter
Eb07 Digital output Enable output relay for unit status (production) or
M5.2 maintenance pre-alert.
Default: Unit status (production);
For further information on relay see paragraph 4.9 Unit status/
maintenance pre-alert contact
7.3.8 Blower unit confi guration (Installer menu)
To best manage the blower units in applications where steam is delivered
directly into the room, the blower on and off times can be set. Delaying
activation of the blower unit allows the system to reach the operating
temperature before the fan is activated. Delaying deactivation of
the blower unit guarantees that parts in contact with the steam will
be completely dried, meaning that when next starting, there is no
condensate in the steam distribution line, avoiding droplets being blown
into the room.
Index Description Parameter
Eb08
Blower units Set the delay time (seconds) for activation and deactiva-
tion of blower units
Defaults: start delay: 0 seconds;
stop delay: depending on the size (30 seconds for
UR002-UR013; 60 seconds for UR020-UR040; 90 seconds
for UR053-UR080)
Possible settings: 0-600 seconds
7.3.9 Save logs (Service and Installer menu)
The log of the main variables can be saved to USB pen drive. The following
variables are logged:
•
Unit On/Off
•
Unit status
•
Active alarms
•
Request (%)
•
Production (kg/h)
•
Level sensor status
•
Fill
•
Drain
The fi le is saved in .csv format. The logs are constantly saved to internal
memory, and are thus exported to the memory key in the USB Host port
by entering menu screen Eb09. Set "Export to USB" to "YES". Progress of
the operation will be shown under "progress".
Index Description Parameter
Eb09 Export logs Save the log of main variables to USB pen drive
Export to USB = Yes, to save the log

7.3.10 Save alarm log
The alarm log can be saved to USB pen drive. To export the file, plug the
USB pen drive into the c.pHC and go to screen Eb10, then set "YES" for
the "Export?" parameter.
Index Description Parameter
Eb10 Export alarms Save alarm log to USB pen drive
Default: No
The fi le will be saved in the pen drive' s root directory and will be called
"AlrmLog.txt".
7.4 Menu E. Settings - c. Confi guration
7.4.1 Main probe (Installer menu)
The main probe can be confi gured on the screen with index Ec01.
Index Description Parameter
Ec01 Main probe Main probe confi guration;
Defaults:
Enable: Enabled (depending on the type of control)
Type: 0-10V
Minimum: 0% r.H.
Maximum: 100% r.H.
Off set: 0
En. Al (enable alarms): YES
Delay: 120 seconds
Possible settings:
Type: 0-10V/0-1V/NTC/4-20mA/0-20mA/2-10V
Minimum: 0-100%r.H .
Maximum: 0-100%r.H.
Off set: 0
En. Al (enable alarms): YES
Delay: 0-999 seconds
For each probe, after having specifi ed the type, the minimum and
maximum values readable by the probe can be defi ned, as well as an
"off set" to compensate for any imprecisions in the value read (example:
off set = 3 %r.H. corresponds to 3 percent increase of the humidity value
read by the probe). Parameter "En. Al. " activates the alarms corresponding
to any probe faults. If a malfunction is detected for a time greater than
the value of "Delay" (seconds), the "main probe broken or disconnected"
alarm is activated.
7.4.2 Limit probe (or second probe - Installer menu)
The limit probe (if present) can be confi gured on the screen with index
Ec02.
Index Description Parameter
Ec02 Limit probe Limit probe confi guration;
Default:
Enable: Enabled (depending on the type of control)
Type: 0-10V
Minimum: 0% r.H.
Maximum: 100% r.H.
Off set: 0
En. Al (enable alarms): YES
Delay: 120 seconds
Possible settings:
Type: 0-10V/0-1V/NTC/4-20mA/0-20mA/2-10V
Minimum: 0-100%r.H.
Maximum: 0-100%r.H.
Off set: 0
En. Al (enable alarms): YES
Delay: 120 seconds
For each probe, after having specifi ed the type, the minimum and maxi-
mum values readable by the probe can be defi ned, as well as an "off set"
to compensate for any imprecisions in the value read (example: off set
= 3 %r.H. corresponds to 3 percent increase of the humidity value read
by the probe). Parameter "En. Al. " activates the alarms corresponding to
any probe faults. If a malfunction is detected for a time greater than the
value of "Delay" (seconds), the "limit probe broken or disconnected" alarm
is activated.
