Automatic Filter Drain Control (Optional)
Automatic filter drain is controlled by a repeat cycle timer that operates a solenoid valve.
Two DIP switches are located on timing device to control drain and cycle times located on
backside of control panel.
Standard factory setting is to drain for 0.1 minute once every 24 hours.
Drain Time (left DIP switch)
0.1 minutes (1 st switch on – all others off)
To
102.3 minutes (all switches on)
Cycle Time (right DIP switch)
1 hour (1 st switch on – all others off)
To
1023 hours (all switches on)
1. Adjust purge air pressure regulator to about 15 psig.
Sample under vacuum: Purge air regulator will control air pressure to educator of
the automatic filter drain. Regulator must be set to provide ample vacuum to
remove filter condensate but not excessive enough to cause interruption in sample
flow to analyzers.
Under positive pressure: Condensate drain flow is directly controlled by solenoid
valve. When solenoid valve is actuated (opened), positive pressure in filter housing
purges condensate out of system through drain line.
2. Initially adjust DIP switches on drain timer to drain for 6 seconds every 24 hours. Time
on switches is additive. Left switch should have only top 0.1 min. switch in the “ON”
position and right switch should have 8 and 16 hr. switches in the “ON” position. Time
periods may need further adjustments after system has been in operation.
Temperature Control
PID Electronic Temperature Controller
1. Press and hold “
” key on the CAL Controls temperature controller.
2. Press either up or down key to adjust setpoint. Setpoint temperature will change one °C
with each press of arrow key.
3. When desired temperature is reached, release both keys.
NOTE: MG-1228, 2812P, and 1235 systems have a low temperature alarm that is
programmed into controller. Default temperature setting for alarm is 5° C below
setpoint temperature. Refer to CAL Controls temperature controller manual for more
information.
