2. Safety Considerations
The DLC-XP/RC is a sophisticated microprocessor based controller for use only with PULSAR
diaphragm metering pumps. It yields tremendous control capacity -- electrical, mechanical and (in
conjunction with the PULSAR pump) hydraulic in nature. In consideration of SAFETY, the user should
be mindful of this relative to his/her safety, that of co-workers and of the process environment. Please
consider the following prior to the installation and operation of a DLC-XP/RC controlled PULSAR
metering pump:
2.1 General Safety
The DLC-XP/RC was designed as a stroke length position actuator for operation solely with the
PULSAR metering pump. Use for any other application is considered un-safe and voids all certification
markings and warrantees.
2.2 Explosive Atmosphere Safety
W ARNING -- E XPLOSION H AZARD -- D O NOT PERFORM INSTALLATION / MAINTENANCE OF ANY
KIND ON THIS DEVICE WHILE CIRCUIT IS LIVE AND / OR THE AREA IS KNOWN TO BE HAZARDOUS .
With the proper marking, the DLC-XP/RC is suitable for use in Class I, Division 1, Group C & D and
Class I, Zone 1, Group IIB or non-hazardous locations only. The DLC-XP/RC will be marked for use
Div. 2 / 2 one 2 or non-hazardous locations only.
The control chassis of the DLC-XP/RC is not suitable for use in a hazardous environment and must be
remotely located in a safe area. Wiring between the two units must conform to local, state, and national
codes and requirements.
2.3 Electrical Safety
The DLC-XP/RC can be considered an industrial controller with an integrated single phase motor
starter. Improper application and use can be hazardous. The user is solely responsible for its use.
Electrical installation must conform to all location relevant electrical codes. Installation and electrical
maintenance must be performed by a qualified electrician. Before installing or servicing this device, all
power must be disconnected from the source at the main distribution panel.
The DLC-XP/RC emits electro-magnetic energy and generates radio frequency interference. Its use is
restricted to industrial applications. The user bears all responsibility for shielding this
energy/interference.
2.4 Mechanical Safety
When properly installed, the device has no external moving parts. The DLC-XP/RC should not be
operated without its cover installed. When under power, the DLC-XP/RC is under computer control
and as such may actuate without warning to the user.
2.5 Hydraulic Safety
Thoroughly review and adhere to the contents of the appropriate pump IOM for installation of your
PULSAR metering pump. As a microprocessor controlled device, the DLC-XP/RC may activate the
pump motor without warning to the user -- generating hydraulic pressure and fluid flow. Care should be
taken to protect both users and system from such conditions.
