Nuvair Auto Drain Timer Operation
Solenoid valve timers can be installed on gas-, diesel-, or electric-powered compressors manufactured by Nuvair. The typical gas-powered compressor timer installation looks like Figure 1. Typical diesel- or electric-powered compressor timer installations look like Figure 2.

Typical for Gas Engines
If your auto drain solenoid timer valve has a fitting on the bottom of the solenoid, like the one pictured in Figure 1, your timing settings are:

[ON] for 5 seconds
[OFF] for 8 minutes

Setting Gas Engine Timers

If you have the typical GAS ENGINE TIMER setup (as illustrated in Figure 1), please follow these instructions to program your auto drain timer:

Press the [MODE] button until “ON-OFF” appears.
Press [ENTER].
Press [ENTER] until the far-right digit flashes.
Press [ADD] until it reads “5”. The display will read “00:00:05”.
Press [ENTER].
Press [ENTER] until the flashing digit is on the third digit from the right.
Press [ADD] until “8” appears. The display will read “00:08:02”.
Press [ENTER] until the “2” starts flashing.
Press [ADD] until the display reads “0”.
Press [ENTER].
The screen will display “ON-OFF” again as the unit saves settings.
Once the new settings are saved, the timer will start counting.

Typical for Diesel Engine and Electric Motors
If your auto drain solenoid timer valve has a fitting going into the side of the solenoid, like the one pictured in Figure 2, your timing settings are:

[ON] for 8 minutes
[OFF] for 5 seconds

If you have the typical GAS ENGINE or ELECTRIC MOTOR TIMER setup (as illustrated in Figure 2), please follow these instructions to program your auto drain timer:

Press the [MODE] button until “ON-OFF” appears.
Press [ENTER].
Press [ENTER] until the third digit from the right flashes.
Press [ADD] until “8” appears. The display will read “00:08:02”.
Press [ENTER] until the “2” starts flashing.
Press [ADD] until the display reads “0”.
Press [ENTER].
Press [ENTER] until the far-right digit flashes.
Press [ADD] until the display reads “5”. The display will read “00:00:05”.
Press [ENTER].
The screen will read “ON-0FF” again as the unit saves settings.
Once the new settings are saved, the timer will start counting.

Manufacturer Instructions

This section contains unedited operating instructions from the 3800 solenoid valve timer manufacturers.

Functions

Adopts flame retardant engineering plastic shell, the solenoid valve timer is safe with high strength.
Controlled by a microcomputer chip, its timing accuracy is high.
Equipped with an LED screen, the timer features of night vision function.
Timing set range: 1Sec～99h59min59Sec, bidirectional adjustable
Mode: Circulation mode (two: switch on first and then switch off, or switch off first and then switch on) One-time mode (one: start at set time)
Power supply: High voltage AC/DC, 110～240V (XY-3800H); Low voltage AC/DC, 7～36V (XY-3800L)
The IP grade of this digital timer is IP65.
Supports standard DIN43650A input/output interface.
LED light indicates the state of ON and OFF.
Applications: solenoid valve and other devices needed to set timing.

Screen Indication

The screen indicates ON―OFF, it is the mode of a switch on first and then switch off.
The screen indicates OFF―ON, it is the mode of switch off first and then switches on.
The screen indicates ON which means switch on first, the cycle time is 1Sec～99h59min59Sec, it is the one-time mode.

Mode and Time Saving
The solenoid valve timer is at factory settings when you use it at the first time, after power on, the timer is at an “ON-OFF” circulation working state. The time of ON and off is both 2 seconds countdown (indicates “0 0 0 0 0 X”, from which X is a decreasing number). If you want to change the mode and time, press the MODE key which shows “ON-OFF”, press the MODE key again it will show “OFF―ON”, and then you can switch to the mode of “ON”, choose the function mode you wanted and press ENTER key to confirm the setting mode, after that you can start to set the time parameters. When you set the time parameters at the state of “ON” (indicates “X X X X X X”), the first digit of the left side starts to flash, that means you can start to set the time, press ADD key for setting increasing time, and then press ENTER key to confirm, after that the second digit of the left side starts to flash, at this time, you can do the same thing to set all of the six bit data when you finish all of the settings, you can start to set the time parameters at the state of “OFF”. All the setting modes are the same as the state of “ON”. When you finish all the setting modes, the timer screen flashes the mode of “ON-OFF” 4 times, and then the timer enters into the working state which is set. When you set up parameters, the system stops working, it will get back to work until you finish the settings; if you do not press ENTER to confirm and exit the setting mode directly, the system is still working according to the settings previously. (The above parameters are taken as an example at “ON-OFF” mode, the other modes are same as which.)

Other Functions
Reset press the RESET key, the digital timer will stop currently working, and then start to cycle working according to the parameters that have been set. Note: this kind of timer is divided into two types: high voltage type and low voltage type. Please choose it according to your actual needs.
