The integration in the operative management and supervision of the logic programmable relay (PLR) MFD-TITAN obtains a faster, precise, trustworthy and simpler operation of the humidifier. Furthermore, it reduces the electrical box components. The PLR MFD-TITAN in our units is a programmable device used to set-up adjust and supervise, in real-time, all the different components which are connected to it. It can work just in the unit or by remote control.
2. General advices. Checking the wiring diagram of the applicable unit is recommended while this operation manual is read. The microprocessor programming has been designed in order that normal operation of the humidifier and ancillaries does not affect to the personal security level. It has been designed according to the EC directives on electric devices and electromagnetic compatibility.
3
Eliminate and/or modify the PLR program will change guarantee conditions, and could affect to the compliance of the EC manufacturing directives and standards. The consequences of new functions will be from the installer or user responsibility. The programmed device is not involved in personal damage security.
Not for standard, only under request.

10. Time basis and U.V lamp
control activation.
In case of restriction of the humidifier operation to a time basis program or to include the use of a U.V lamp, in this activation mode, it is possible to:
! !
Activate the arrangment for the unit operation subjected to the programmed time cycles as per settings in the ADJ mode. Activate the U.V lamp operation, for the diferent operation cycles.
! Press >, the password line will blink; to move the cursor on the line, use the < or > buttons. ! To change the numbers, press the or V buttons. ! The password number will be the wiring diagram number of your machine (Ex. W.D: F-1234 will be 01234 password). ! confirm by pressing OK.
When the time basis option is activated, the humidifier operation is restricted to the ON periods settings done on the ADJustment mode and to the chosen configuration mode: ! ! !
Stage controller (S). Proportional controller (P). Set point control (M).
When the U.V lamp option is activated, the humidifier different cycles will introduce the U.V lamp operation, restricted to the 3 different configurations shown above. TIMES BASIS AND U.V LAMP “ACTIVATED” Remark: The activation or desactivation of the time basis control or the U.V lamp go separately.

11. ADJustment menu. In the ADJ mode there are 5 SUB-MODES:
DAY TRANSLATION
1º) Humidity sensor set point. 2º) Weekly program (HW). 3º) Annually program 1 (HY1). 4º) Annually program 2 (HY2). 5º) Drain cycle during continuous operation. 6º) Drain cycle after operation.
Lunes (LU)= Monday; Martes (MA)= Tuesday; Miércoles (MI)= Wednesday; Jueves (JU)= Thursday; Viernes (VI)= Friday; Sábado (SA)= Saturday; Domingo (DO)= Sunday
11.1. Humidity sensor set point: If the measured signal “M” configuration has been selected; the requested humidity set-point (Hr), the OFF-SET point (Os) and the Hysteresis point (Hy) could be fitted. For more details about this adjustment go to point 11.
11.2. Weekly program (HW):
! To modify any variable:
If the time basis control is activated, this function should be adjusted. The display shows : The interval of days in which the unit is working each week. (example : from Tuesday to Sunday both included). The interval of hours in which the unit is working each day.(example : from 15:10 to 21:00 all days from Tuesday to Sunday).
11.3. Anually program 1 (Hy1): If the time basis control is activated, this function should be adjusted. The display shows : Line 1 : “OFF” date (For example 05/02/06). Line 2 : “ON” date (For example 02/01/06). Remark: The reason to have 2 different yearly programs is to set two different operation seasons in a year.
v Press OK. v The superior line will blink. v Select the line you need modify with the arrows or V. v When the line is selected, press OK. v To move the cursor on the line use the arrow < or >, use the arrows or V to change the digit you want to modify. For a completely change, modify each digit. v To confirm all the data press OK. v Do the same for the second line.
11.4. Anually program 2 (Hy2): If the time basis control is activated, this function should be adjusted. The display shows : Line 1 : “OFF” date (For example 11/04/06). Line 2 : “ON” date (For example 06/03/06). Remark: The reason to have 2 different yearly programs is to set two different operation seasons in a year.
v Press ESC to exit.
! REMARK: For the anually program desactivation of Hy1 or Hy2 just program one with the same date of activation “ON” and desactivation “OFF”. 11
11.5. Drain cycles during continuous operation:
Remarks: V
In this sub-mode, the drain cycle frequency can be set forthose cases when the humidifier is working continuously, in order to achieve a renewal of the basis water. We recommend a 24 H - 48 H drain cycle frequency.
11.6. Drain cycle after operation: Further to set the drain cycle during operation frequency, it is necessary to set three values of running time:
v v v v v
The pad irrigation turns off during the drain process. Zero setting does not allow the humidifier operation. Drain cycle timer counts from the isolator switch I1 turns on. The minimum possible interval is 1h. The maximum possible interval is 200h. When the unit switches off by the isolator switch I1, the drain timer stops too.
To modify any variables: v v v v v
Press OK. The superior line will blink. Select the line to modify with the arrows or . When the line is selected, press OK. To move the cursor on the line of the time (min.: sec.) use the arrow < or >, use the arrows or to change the digit you want modify. To change the hour completely , modify each digit. v To confirm all data press OK. v Press ESC to exit.
11.6.1. Draining time during operation: The draining valve V1 opens (example 5min) when the drain cycle timing during continuous operation is reached. This valve V1 opening time can be chosen according to the size of the humidifier / basin capacity. Figures between 5 and 15 min are reasonable, and such figure should be higher than the valve V2 opening time.
11.6.2. Fill valve to help flushing: This upper figure sets the simultaneously opening time of the fill valve V2, to help the solids content in the basin be drained away. A suitable figure might be 4-5 min less that the drain valve opening time.
11.6.3. The drain time after operation: Whenever the humidifier is off because of the connection (H1) or the I2 switch, the drain valve opens after a 4 hours delay, in order to empty the basin. This is the opening V1 drain valve time to empty the basin (example: 60min.) We recommend a 30-60 min emptying time.
