ISIMET LA / LSP - CONTROLLER MAINTENANCE CHECKLIST
VERIFY THAT ALL MAINTENANCE PROCEDURES HAVE BEEN PERFORMED.
Refer to pcb Configuration Chart, Maintenance Slide & Maintenance Guide for Instructions in performing these tests.
Maintenance Instruction:
Maintenance should be performed only by a qualified service technician. ISIMET recommends that testing be
performed at least every six months, but always prior to utilizing the system when it has been left dormant or not
used for an extended period. Additionally, at least annually, service all solenoids following the recommended
procedures in the Solenoid Slide Presentation.
The start-up tests as described in the Product Operation & Maintenance Manuals and Slide Presentations should be
conducted periodically to insure that the control system operates as intended. Input and output interface is an
available option. Therefor, testing for proper interface between the input devices and automation systems, and
output notification monitoring devices and automation systems should be conducted to verify communication
between the Controller and these devices and integrated automation systems.
The output operators should be tested for correct voltage, amperage, and registered ohms. Ohms should be
registered using either an analog or digital meter with power OFF to the unit. So that the intended safety provided
for by optimum performance of the system, the proper operation of these operators should be periodically tested
and verified.
Complete the test summary on page two and the checklist found on page three for each independent control system.
A typical test sheet is provided on page four as an example and where system configuration and performance
matches this example, then it may be used as the completed test sheet. If using the example for test reporting and
where an specific application noted on the report does not apply to the tested system, strike through that portion of
the report.
If testing indicates that a component is failing or no longer operates as intended then that device should be repaired
or replaced immediately. If the communication test fails between the Controller and either a remote monitor or
system then steps should be taken immediately to determine the cause of this failure and then make needed repairs.
Warranty - Liability Criteria:
During the terms of warranty, the testing should be performed and transmitted to ISIMET by fax, e-mail or mail.
ISIMET does not warrant against or assume liability for failure of operation or lack of notification to secondary
integrated monitoring systems. Warranty excludes Solenoids or Electrical Contacts other than those provided by
ISIMET.
