DESCRIPTION:
Herschel Infrared’s Fan Purge Timer is designed for use with the Vulcan Industrial heater. It can be used in Single
or 3-phase Vulcan installations.
The Fan Purge timer sits downstream of the circuit controller (Contactor, Thermostat, PIR or PLC Control) and
will switch on the Vulcan’s fans when current is detected on any of the phases powering the heater. When set
up following these instructions, the Fan Purge Timer will leave the fans running for between 2-3 minutes after
current to the heater has been switched off.
The Fan Purge Timer does not carry any of the heater’s electrical load, so typically only 1 unit is required for each
3-phase circuit. Maximum current on the fan circuit is 5 amps which should be more than adequate to power all
the fans on the heaters on a given circuit. (Each fan consumes only 20 Watts so 5 amps implies up to 14 x 9-
12kW units or 28 x 5kW units).
INSTALLATION:
Fix the Fan Purge Timer to a wall by drilling 2 holes
70mm apart; insert rawlplugs and use 2 pan-headed
screws through the fixing centres in the back of the
box to secure the box to the wall.
ELECTRICAL CONNECTION:
Remove the 3 blanking covers at the bottom of the plastic box and Insert the 3 cable glands supplied with the
Fan Purge Timer into the 3 holes.
Connect a permanent 240V electrical supply to the terminals on the far left marked “240V IN FAN”) and take out
the Live & Neutral Fan Output (Marked “Fan O/P”) to power the fans.
Connect Line 1, 2, 3, Neutral and Earth from the 3-phase circuit to the terminals on the far right (Marked
“Sense”). For Single Phase installations, connect the Live lead to the L1 terminal.
OPERATION
IMPORTANT! Before First use, use a small screwdriver to set the Purge Timer to
50% (approximately 2½ minutes). (Turn so the slot in the timer points straight up.)
The Green “POWER” LED will be lit when electrical supply to the unit is present (and
should therefore always be on).
The Red “STATUS” LED will light continuously when current is detected on any of L1,
L2 or L3 and the Cooling fans will run.
When current is no longer detected on any of L1, L2 or L3, the unit will go into Purge
mode. The Vulcan lamps will be OFF but Fans will continue to run for 2 minutes.
The Red “STATUS” LED will flash during Purge mode.
When the Red “STATUS” Led is off, this indicates both the heaters and the fans are OFF.
TEST AND VERIFY THE ABOVE IMMEDIATELY FOLLOWING INSTALLATION. DO NOT ALLOW VULCAN LAMPS
TO OPERATE WITHOUT THE FANS RUNNING.
