Any equipment connected to RS232 must be certified to IEC 61010-1/ IEC
60950-1/ IEC 623681 should be connected to the DB-9 port.
Only JULABO approved cable must be used to connect Flow meter to the
unit. Refer to Spare Parts to order this cable.
High Temperature Limit on Coolant Return - The maximum allowable
coolant return (inlet) is 50°C. It is the responsibility of the customer to
ensure that this limit is not exceeded. JULABO recommends a thermal
shutoff be used in conjunction with the equipment being connected to the
Recirculating Chiller. Methods include:
A method to turn off the heat load from injecting additional heat
o
into the coolant. This will allow the Recirculating Chiller to reduce
the temperature of the coolant further until stable.
A method that stops or restricts the coolant flow into the
o
Recirculating Chiller. This will result in a Coolant High Pressure
alarm, which will shut down the system for safety.
A method that interrupts the power to the Recirculating Chiller.
o
If any of these methods are activated, please reference the Alarms section.
NOTE
The manufacturer is not liable for damage occurring when using the unit in a
way it was not intended. This also voids JULABO' warranty.
